Pyrite Mining | Mining History of Louisa County, Va
Pyrite Mining began in the Mineral area as early as 1834. The mines were successfully and intermittently worked for iron, copper and pyrite. During the period of most intensive development, 1882-1905, the mines were operated for pyrite although some lead and zinc was recovered. ... Electricity allowed the mine and processing plant to operate 24 ...

Retreat mining is the last phase of a common type of coal mining technique referred to as room and pillar mining. Retreat mining is a process that recovers the support-ing coal pillars, working from the back of the mine toward the entrance, hence the word retreat. Room and pillar mining advance inward, away from the entrance of the mine.

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.

Effects of pyrite on the spontaneous combustion of coal
The results indicate that pyrite can nonlinearly accelerate the process of spontaneous combustion. The coal sample with a pyrite content of 5 % has the largest CO release rate and oxygen adsorption as well. However, the coal sample with a pyrite content of 7 % has the largest rate of heat flow according to the results from the DSC tests.
