Pyrite Mining Processing Equipment Flow Chart Cases ...

2021-12-25  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.

Pyrite - an overview ScienceDirect Topics

Pyrite oxidation begins with the oxidation of sulfur by oxygen yielding sulfate, ferrous iron, and acidity. The rate-limiting step is the oxidation of Fe 2+ to Fe 3+, which occurs only very slowly at low pH chemically, but is catalyzed by bacteria that speed up the reaction rate by a factor of 100 000. Once underway, the process of pyrite oxidation may continue until the source is exhausted.
