Under the oxidation process in the presence of air, pyrite causes acid mine drainage to release sulfuric acid and heavy metals, which is a serious environmental problem and a concern in the mineral industry. As a semiconductor material with redox behavior, pyrite can cause a galvanic effect when in contact with other minerals [5, 6]. It …

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.
