Pyrite Mining Processing Equipment Flow Chart Cases ...

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.

processing of pyrite - livraisonpizzabourgenbresse

Jan 13, 2010 Pyrite (FeS 2) is a major mining waste product and natural sulfur mineral as well (Lin and Huang 2008).Since sulfur on its surface rapidly oxidizes when aerated, the sulfate formed would result in acid mine drainage (Nyavor et al. 1996).During the process of surface oxidation and subsequent dissolution of pyrite, some dissolved heavy metals would be released, leading to heavy ...
