re: questions to reduce my ignorance Westmoon,
I don't know where they are up to, but in my mind, things that may be more difficult to get or long lead time include:
Crushers and grinding mill, the other part of this is the design of the footing, foundations, layout and structure, not to mention final lift heights, conveyor power ratings etc etc.

Stainless steel tanks should be ok, but 316 SS thickeners might be a problem. other than that, electrical items including transformers but also VF drives on larger items could be a (probably) small problem.

Then there is the biggest shortage. Skilled labour, probably electrical engineering wise, associated with control system design, implementation, troubleshooting.

But good planning should negate most of these.

Shumsta:
yes you are correct, one solution with many different metals in it, some valuable, others not. That solution is passed through as many different processes as required to form different concentrates or pure metals.
This solution is then also recycled to the front of the process to conserve reagents.
