Leaching of pyrite with hydrogen peroxide in sulphuric acid

1997-8-1 · The kinetics of leaching pyrite with hydrogen peroxide in sulphuric acid were investigated. The parameters studied were: stirring speed, temperature, particle size and concentrations of H 2 O 2 and H 2 SO 4.The effects of SO 4 2− and H + additions were also investigated. The leaching rate decreases with increasing stirring speed and H 2 SO 4 …

Pyrite Mining | Processing Equipment | Flow Chart | Cases

2022-6-24 · 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.
