pyrite mining processing
Ask The Experts
The other possibility is shipping to a custom milling operation that can process the pyrite, but shipping and processing can be expensive. If you are a small miner, it may not be economically worthwhile to recover that gold inside the pyrite. For large tonnages, big commercial mines oxidize their pyrite in roasters or autoclaves.
