VANCOUVER: After a nine-year lull, investors are fast-taking notice of the once-neglected precious-metals sector. Gold was among 2019’s best-performing asset classes and it was only days into the arrival of the Covid-19 pandemic before the metal regained its USD 1,700/oz footing from a low of $1,471.
On 21 April, Bank of America predicted a gold price of $3,000 per ounce within 18 months suggesting that AU could continue to outperform even if the Covid bear-market continues. In line with predicti
Buying used heavy machinery can be a good or a bad experience, depending how you do it. If you are purchasing or are considering to do so, there are some steps that you should do before.
An independent inspection report
When you hire the services to perform an independent inspection, this can help ensure that the used machinery you are buying won't be heading to the workshop sooner than you expect. It's true that there are no standards for how to inspect a machine and how the reports are done, bu

Mining is essential to the global economy. After all, there would be no such thing as an iPhone without mining.
Mine operators around the world are under pressure to produce in a difficult environment that goes through cycles of boom and bust depending on commodity prices. Every possible efficiency is explored as they try to stay competitive.
For surface mine operators, one of the most critical pieces of equipment is the haul truck that moves rock and ore to the crusher

The density of steel balls is approximately 7.6-7.8g/cm³, while the density of ceramic balls is generally 3.6-3.8g/cm³, roughly half that of steel balls. When the filling rate of the ball mill remains unchanged, the lower density results in the grinding media being half as heavy, reducing the load on the ball mill and consequently lowering the current. If the grinding efficiency and hourly production of the mill remain unchanged, the power consumption for grinding will inevitably decrease.

This article highlights a death that took place in a bus maintenace shop. But it could have happened in any shop. Maybe even one like at your mine site. It also looks at infiltration of CO gas into aother areas. And the limited time people have to get clear of an area with CO gas build up.
"That was a situation not anticipated by a school bus contractor and it had never happened before," the
Underwater blasting, often known as submarine blasting, is used for a wide range of purposes. This includes harbor and channel widening, trench excavation for establishing oil and gas pipelines and communication cables, demolition operations, and substructure construction. Particularly, underwater rock blasting is the most difficult and least understood source of vibration, which may have a significant impact on the safety of neighboring buildings and structures, especially berthing structures.

In the unlikely event of a 7495 Shovel being Struck by lightning, The shovel itself will act as a Faraday cage given the fact that it´s built of conductive metal and solidly connected to ground by the crawlers.
If during maintenance/servicing a 7495 Shovel you´re caught into a weather alert and are not able to evacuate, consider the Shovel as a shelter, go into the operator cab and make sure all windows are up. Do NOT leave the Shovel until all weather alerts have been cleared.
Have a safe Weekend
