Pyrite Mining Processing Equipment Flow Chart

2021-3-16  What is Pyrite. Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Ask The Experts - How do I recover gold in pyrite?

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.
