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.

Nevada Iron: There is More than Gold in the Nevada Desert

Iron is very common and occurs in high concentrations in many deposits, but it is easiest and cheapest to extract from iron oxide minerals like magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). While iron often occurs within sulfide minerals like pyrite (FeS 2), extraction from sulfides is not economic.
