There are a few mining companies out there producing battery grade lithium from Spodumene (LiAlSi2O6), but would anyone know if there is a metallurgical process to produce LiOH or Li2CO3 from Petalite (LiAlSi4O10)?

The process is the same as the spodumene but with a lot more heat. That is why is not economically viable yet.
At this moment (july/2023) spodumene is the only profitable lithium ore on LCT-pegmatites (commonly we say hard rock). We have pilot plants for lepidolite, amblygonite-montebrasite, and jadeite (also lithium-bearing minerals for hard-rocks). The process to get to the commodities is still evolving.
