Manufacturer teaches you how to distinguish the quality of the rubber conveyor belt, good quality or cheap quality 





First of all, we need to have a comprehensive understanding about your actual transportation situation, and then assess it according to the method, quantity, size, etc, finally select the appropriate conveyor belt. When you select, it is necessary to ensure the integrity of conveyor belt body, so that there will be no jamming or breakage during use. 

Secondly, it is necessary to effectively distinguish whether the conveyor belt is easily scratched, the glossy flat thickness.

l The high quality conveyor belt can withstand more loads, and the transportation angle will be improved due to the change of objects during use, thus ensuring the safety of the material.

l The inferior conveyor belt has a fixed load-bearing capacity. In the process of transportation, it is easy to cause the conveyor to stagnate due to the insufficient thickness or insufficient quality, and evenly the cargo may fall off. 


The good rubber conveyor belt is a necessary equipment for the transportation process of the enterprise. Therefore, in the process of selection, it is necessary to carefully study and consult the relevant staff in details, understand the basic attributes of the rubber conveyor belt, thus it will guarantee the stability of equipment operation and more secure. 

Specific easy effective methods to identify the quality of the conveyor belt:

1.     Firstly, look at the rubber surface of the rubber conveyor belt, the rubber surface of a good rubber conveyor belt should be smooth and flat, no bubbles, gullies, dryness and so on.

2.     Finger press: Nail pinches the rubber surface, the rubber conveyor belt with high rubber content will not be smashed or broken, and the scar will recover in 3 to 5 seconds.

The rubber conveyor belt with low rubber content will recover slowly, or no recovery.

3.     Odor: The rubber conveyor belt with high natural rubber is not the pungent, light smell.

But the rubber conveyor belt with high reclaimed rubber has a very scent, pungent, you smell, you will be not comfortable!

4.     Check the core: The high quality rubber conveyor belt has the same layered core, and the layer of rubber and fabric is even thickness.

And the inferior conveyor belt will have a different thickness, pits.

En segundo lugar, es necesario distinguir efectivamente si la cinta transportadora se raya fácilmente, si el grosor es plano brillante.

l La cinta transportadora de alta calidad puede soportar más cargas, y el ángulo de transporte se mejorará debido al cambio de objetos durante el uso, lo que garantiza la seguridad del material.

l La cinta transportadora de inferior calidad tiene una capacidad de carga fija. En el proceso de transporte, es fácil hacer que el transportador se estanque debido al grosor insuficiente o la calidad insuficiente, y la carga puede caerse de manera uniforme.  


La buena cinta transportadora de goma es un equipo necesario para el proceso de transporte de la empresa. Por lo tanto, en el proceso de selección, es necesario estudiar cuidadosamente y consultar al personal relevante en detalles, comprender los atributos básicos de la cinta transportadora de goma, por lo que garantizará la estabilidad de la operación del equipo y más seguro.


Métodos específicos fáciles y efectivos para identificar la calidad de la cinta transportadora de goma:


1. En primer lugar, observar la superficie de goma de la cinta transportadora de goma; la superficie de una buena cinta transportadora de goma debe ser lisa y plana, sin burbujas, barrancos, sequedad, etc.


2. Prensa de dedos: el clavo pellizca la superficie de goma, la cinta transportadora de goma con alto contenido de goma no se romperá ni se romperá, y la cicatriz se recuperará en 3 a 5 segundos.

La cinta transportadora de goma con bajo contenido de goma se recuperará lentamente o no se recuperará.


3. Olor: la cinta transportadora de goma con alto contenido de goma natural no es el olor penetrante y ligero.

Pero la cinta transportadora de goma con la alta recuperación de goma tiene un olor muy fuerte, acre, huele, ¡no se sentirá cómodo!


4. Verifique el núcleo: La cinta transportadora de goma de alta calidad tiene el mismo núcleo en capas, la capa de goma y la tela es de espesor uniforme.

Y la cinta transportadora inferior de goma tiene un espesor diferente, pozos.

During the 24th week of the year (June 10th to June 16th, 2019), at least 20 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, the illegal blockade on Newmont Goldcorp’s Peñasquito mine in Zacatecas was lifted after 81 days, with negotiations between the parts to start on the following week. CAMIMEX proposed 90% of the Mining Fund should be allocated directly to the mining communities, this amid the presidential intention to use this fund at his sole discretion. ON EXPLORATION, In Baja California, One World Lithium completed the drilling program at Salar del Diablo. In Sonora, Aloro completed a drilling program at Los Venados; Ridgestone presented results of a bulk sample program at Rebeico. In Chihuahua, Ethos Gold commenced drilling at Purisima; Kootenay completed road building for its incoming drill program at Columba; Sable completed its second drilling campaign at Margarita; Radius reported results from drilling at its Amalia project. Advance Gold completed a 3D model for its Tabaqueña project. In Veracruz, Azucar presented results of seven more drill holes at El Cobre. ON MINING, No relevant news. ON FINANCING, Mako is to raise C$27 M, Aztec C$360 K and Minera Alamos had $400 K in warrants exercised. ON RESOURCES AND DEVELOPMENT, Mexus Gold started leaching at Santa Elena, in Sonora. Oroco clarified a statement on Santo Tomas resources from a previous news release. Impact Silver released sample results for the Manto America target area at Zacualpan. Candente informed positive results by partner Sun River Gold on metallurgical tests for the El Oro tailings. ON DEALS AND CORPORATE ISSUES, No relevant news.


  • The illegal blockade on Newmont Goldcorp’s Peñasquito mine in Zacatecas was announced to be lifted on June 13th. Discussion panels between the parts are to be held starting on June 19th, sponsored by the Ministry of the Interior. The illegal blockade by a truck contractor and proprietors of communal land near the mine site lasted for 81 days. The truck contractor says it is fighting for employment whereas the communal proprietors claim water shortages caused by consumption by the mine (and the company alleges a plain extortion attempt).
  • CAMIMEX (Camara Minera de Mexico) proposed that 90% of the resources of the Mining Fund (Fondo Minero) stay within Municipalities, and the remaining 10% with the Mining Secretariat. Fernado Alanis, president of CAMIMEX, said that the original objective of the fund was to support the mining communities. On the former regulations only 50% of the funds reached the municipalities and the remaining to the coffer of the Federation and States, “but we believe the majority should reach the localities” (this proposal comes amid the presidential intention to deliver the Mining Fund as loans to people in mining communities, a move most in the industry see as a play to gain support for elections, and not helpful for supporting mining communities, originally the aim of such fund).


  • Ethos Gold Corp. commenced its drill program in the Purisima property in Chihuahua. The initial program will comprise 3,000 m of reverse circulation (RC) drilling in 15 holes, targeting shallow oxide bulk tonnage gold mineralization. “At La Purisima a northwest trending gold mineralized zone has been identified over a strike length of at least 2 km with a width of alteration and geochemically anomalous gold mineralization of approximately 600 metres. Within this footprint are two north-west striking zones that have the strongest gold anomalies, each approximately 200 metres wide.”
  • Aloro Mining Corp. completed 1,347 m of drilling in four holes at its Los Venados project in Sonora. The program aimed to test a blind mineralized felsic dome structure adjacent to the Mulatos mine’s high grade Escondida gold bearing felsic dome. Relevant intercepts comprise 3.05 m @ 0.14 gpt Au; 1.53 m @ 0.13 gpt Au; 3.05 m @ 0.22 gpt Au; 7.62 m @ 0.16 gpt Au.
  • Kootenay Silver Inc. has completed road building and signed a surface access agreement with the landowner at its Columba property in Chihuahua. Drilling is expected to start on the third week of June 2019.
  • Sable Resources Ltd. announced the completion of the second round of drilling at the Margarita project in Chihuahua, releasing the results of the last 15 holes. Here some of the highlighted results: 5.7 m @ 39 gpt Ag; 11.55 m @ 35 gpt Ag; 4.15 m @ 35 gpt Ag; 7.65 m @ 42 gpt Ag; 7.60 m @ 63 gpt Ag, 0.75% Pb, 0.56% Zn (125 gpt AgEq); 8.45 m @ 93 gpt Ag (including 3.2 m @ 193 gpt Ag); 6.0 m @ 66 gpt Ag; 5 m @ 166 gpt Ag (including 1.5 m @ 426 gpt Ag); 62.5 m @ 28 gpt Ag; 59.5 m @ 68 gpt Ag (including 3.05 m @ 230 gpt Ag and 1.75 m @ 220 gpt Ag and 1.65 m @ 190 gpt Ag, and 5.60 m @ 153 gpt Ag); 32.90 m @ 34 gpt Ag; 17.90 m @ 23 gpt Ag.  
  • One World Lithium Inc. announced the completion of two more holes at its Salar del Diablo project in Baja California.
  • Ridgestone Mining Inc. released results of a bulk sampling program on its Rebeico Cu-Au project in Sonora. A total of 111 samples weighing a combined 2,500 kg were collected from dumps, mainly form the Alaska vein which operated up to the 1960’s. The average grade for the different zones was: Veta Grande, 6.7 gpt Au, 13 gpt Ag, 0.79% Cu; Upper Alaska, 3.3 gpt Au, 11 gpt Ag, 1.39% Cu; Lower Alaska, 3.4 gpt Au, 23 gpt Ag, 1.32% Cu; La Verde, 3.5 gpt Au, 12 gpt Ag, 0.37% Cu; Josefina, 0.24 gpt Au, 12 gpt Ag, 0.49% Cu; Tunel de Garcia, 2.1 gpt Au, 2 gpt Ag, 0.40% Cu; Año Nuevo, 1.0 gpt Au, 5 gpt Ag, 0.60% Cu; Elena, 0.1 gpt Au, 5 gpt Ag, 0.99% Cu.
  • Radius Gold Inc. reported results from its 1,756 m six diamond hole second phase drill program at its Amalia project in Chihuahua. With the majority of assays received the highlighted true width intervals are: 44 m @ 12.38 gpt Au, 309 gpt Ag; 4 m @ 1.05 gpt Au, 24 gpt Ag; 4 m @ nil Au, 647 gpt Ag; 24 m @ 2.3 gpt Au, 126 gpt Ag (including 2.6 m @ 9.85 gpt Au, 761 gpt Ag); 65 m 3.75 gpt Au, 61 gpt Ag (including 17 m @ 7.91 gpt Au, 65 gpt Ag). “Radius and its partner Pan American Silver Corp have now completed two drill programs totalling 3665m in 15 drillholes…. Geological controls on the mineralization are complex with multiple events of gold and silver mineralization within veins, stockworks and hydrothermal breccias.”
  • Advance Gold Corp. announced the completion of a 3D model for its Tabasqueña project in Zacatecas. “Drilling in the first 3 phases has hit a cluster of mineralized epithermal veins over an area from east to west of approximately 300 metres, and north to south 400 metres, and 300 metres of depth”.
  • Azucar Minerals Ltd. released results from the Norte and El Suegro zones at its El Cobre project in Veracruz. Highlighted results comprise: 19.30 m @ 0.64 gpt Au, 0.08% Cu and 103.40 m @ 0.33 gpt Au, 0.11% Cu in one hole; 29.95 m @ 0.12 gpt Au, 0.15% Cu; 494.50 m @ 0.16% Cu. 0.16% Cu (including 64.5 m @ 0.27 gpt Au, 0.17% Cu); 67.85 m @ 0.46 gpt Au, 0.2% Cu (including 36.2 m @ 0.68 gpt Au, 0.27% Cu); 112.0 m @ 0.17 gpt Au, 0.26% Cu (including 57.75 m @ 0.22 gpt Au, 0.40% Cu); 200 m @ 0.18 gpt Au, 0.22% Cu (including 34.5 m @ 0.36 gpt Au, 0.28% Cu); 101.05 m @ 0.47 gpt Au, 0.14% Cu

  • Mako Mining Corp. is to conduct an offering to raise gross proceeds of C$27 M (La Trinidad, Sinaloa).
  • Aztec Minerals Corp. has arranged a non-brokered private placement financing to raise minimum gross proceeds of CAD$360 K (Cervantes, Sonora).
  • Minera Alamos Inc. warrants for an amount of $400 K were acquired by Donald Smith Value Fund, L.P. Following the acquisition the acquiror holds 10.8% of the outstanding common shares of Minera Alamos, of which previously held 9.8% (Santana, Sonora; La Fortuna, Durango).


  • Mexus Gold US. informed leaching has started at its Santa Elena mine in Sonora (not to mistake with First Majestic’s Santa Elena mine, also in Sonora). “Approximately 5700 tons of high-grade quartz vein material will be broken on site and hauled to the crushing and leaching site. The estimated grade for this material is in the order of 5 to 10 g/t Au.”
  • Oroco Resource Corp., at the request of IIROC clarifies a previous news release. The Mintec Inc. resource estimate included in the historical Bateman Report of 1994 for the Santo Tomas project in Sinaloa utilized a classification scheme other than those set out in NI-43-101. “A qualified person has not done sufficient work to classify the historical estimate as a current mineral resource or mineral reserve. However, the historical assaying and verification methods were performed within the accepted standards applicable at the time.”
  • Impact Silver Corp. released results from surface and underground sampling at the Manto America target area on its Zacualpan property in Estado de Mexico. More than 33 samples have returned greater than 2 gpt Au, peaking at 22.40 gpt Au. Highlighted results include 0.50 m @ 22.4 gpt Au, 7 gpt Ag; 0.40 m @ 21.7 gpt Au, 101 gpt Ag, 1.2% Pb, 1.4% Zn; 0.30 m @ 20.40 gpt Au, 43 gpt Ag; 0.2% Pb, 0.4% Zn; 1.20 m @ 19.5 gpt Au, 8 gpt Ag; 0.30 m @ 16 gpt Au, 421 gpt Ag, 0.8% Pb, 2.1% Zn; 0.37 m @ 14.5 gpt Au, 14 gpt Ag; 0.30 m @ 7.1 gpt Au, 17 gpt Ag; 1.0 m @ 6.4 gpt Au, 2 gpt Ag; 1.0 m @ 3.1 gpt Au, 41 gpt Ag, 0.6% Pb. “The mineralization is hosted in strongly argillically altered volcanic rocks and is associated with lead and barium suggesting a volcanogenic massive sulphide provenance similar to the Capire silver lead zinc deposit to the south”.
  • Candente Gold Corp. informed that Sun River Gold has reported very positive recoveries from metallurgical testing of samples from the tailings deposit at its El Oro property in Estado de Mexico. The tailings project is being moved forward by negotiating the purchase of land for the new processing area and the obtaining the required permits. The material tested was from auger drilling conducted in 2018, averaging 2.99 gpt Au, 85 gpt Ag. Flotation tests were conducted on -325 mesh material returning an average recovery of 80.1% Au, 67.5% Ag on the Upper, Middle and Lower sections of the tailing, and an average of 75.6% Au, 63.6% Ag recoveries in blended material.

You send me many letters asking me to write my business plan. It is right that you are interested in my opinion. I worked in different universities of the world. I communicate a lot online with different people.

I can share my independent opinion about mining in the world. Everywhere is the same. They promise to do this work and go to the laboratory to do experiments. Next on luck. It turns out or not. 

There is no laboratory in the world has enough equipment and specialists to create new generation technologies. Problems are growing. Traditional types of ores are running out but for new ores there is no technology.

I did a little calculation. How much money is needed to create a modest modern ore benefication laboratory.
1. Buildings and facilities – 20 million dollars
2. Equipment and apparatus – 15 million dollars
3. Monthly expenses are more than 15-20 million dollars per month.

At full load, this laboratory and design organization can perform work for a maximum of 2-3 million dollars per month. This whole company of specialists from around the world will be able to perform work only in a close-knit team: because each of them knows only his own problem and does not control the whole situation in the complex.

This means that every month you lose 18-12 million dollars per month (216-144 million dollars a year). You also spent another 35 million on equipment and building. Also You have to spend several million on staff training.

Let’s say that you went the traditional way. You invested hundreds of billions of dollars (for 50-100 years). You have trained hundreds of new specialists, opened new research institutes and laboratories, and issued hundreds of scientific grants. And so, 50-100 years passed, but a miracle did not happen. If you have not yet done this, then stop, and do nothing.

Universities understand that they have no such opportunities, but they really want the money. They create a fairy tale for investors on paper. Next to the sign that this is a student’s educational laboratory of ore beneficiation, new ones will appear: Innovation Center, Technology Center, Technology Certification Center, Certification Center of raw materials (ore, waste), Center for complex processing of raw materials, Laboratory for waste processing and so on.

If earlier it was a backward laboratory with old non-working equipment measuring 100 square meters, now, according to documents, this is a certified scientific center measuring 200-600 square meters and with the latest stunning equipment worth millions dollars.

They enter into their documents famous people who do not even know it. I learned many times that someone enrolled me in my project or scientific school without my consent and permission.

They draw up the necessary documents and begin to search for the simpleton. However, they have no idea what they will do.

I know many such examples. If a researcher can just “eat money” for years without getting the expected final result, then he will do so (Murphy’s Law). The increase in funding for research will only exacerbate this situation.

I suggest that you bypass the path of traditional development.

I considered the costs and did not create a laboratory. I created “PETROVSKY´S MATRIX”.
For many years I have been working on creating a “Mineral Benefication Information System”. I create it with my own money and am the only copyright holder.

This system you need. I don’t need it.

I can create 5 competing technologies for any ore without any information system. It is very difficult and only I can do it. In fact, “Mineral Benefication Information System” will be my only competitor.

You need my “Mineral Benefication Information System” and “Petrovsky’s Matrix”.

No need to teach anyone. For this, you will need centuries of hard work and the abandonment of all your stereotypes, theories and delusions. I think that for you it is almost impossible in the near future.

You need just to create a my smart system and let it work.

You do not need hundreds of specialists in the field of mining, but only a few people to interact with the expert system”Mineral Benefication Information System”. An independent expert system will describe the real situation (only if it is correctly taught) and will give you the accurate way of solving the problem.

Therefore, if we are talking about relatively small investments (about USD 10-20 millions), then I can recommend you to invest in me, this is the most reliable investment.
So, my business plan is an investment in me and under my name. Then we decide what is best for you, we can determine in detail the larger investments (under USD 1 billion and more).

You choose.

Sincerely, Ph.D. Natalia Petrovskaya

Interested to get feedback from mining professionals regarding rubber wear linings in terms of technical needs and requirements?  Do existing wear linings for bucket reclaimers, trucks and chutes perform as required and have a long enough life? 

Could quarries and mines benefit in terms of cost savings or production output yields if wear linings and conveyor belting had a longer life in use?

Are there any major elastomer wear lining problems that currently need a solution and extended life in use?

What expectations would a mining professional have in terms of technical performance and the lifecycle of the wear lining or belt product?

OHS. Dust safety.

Dear Mining Industry Professionals,

I am working in Occupational Health and Safety field, specifically in mining and quarrying.

I'm happy to share the news about occupational dust-related diseases like silicosis, "black lung" etc. along with regulations and recommendations to protect workers from dust exposure.


Here is the first article about respirable crystalline silica regulations update.

OSHA developed the guidance to employers and employees regarding final rule regulating occupational exposure to respirable crystalline silica in general industry. 81 Fed. Reg. 16286. "OSHA noted that the use of clothes-cleaning booths would be permitted because although such booths use compressed air to clean clothes, the dust is “blown out of the employee’s breathing zone and is captured by a filter.” 81 Fed. Reg. at 16797."

I am a mid-career mechanical engineer, and I am cosnidering a career change with the mining industry as my top area of interest. I have a long held fascination with the industry as my father, an accomplished geologist, worked in the exploration side for many years.

My question for members is this: I would expect there is always a training process for new hires at any company,but for someone who has been out of school for a couple of decades, what essential training, certification work or schooling can one add to their resume or academic background to make them a stronger candidate for employment in this field?
