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.

Ultrafine Grinding - an overview | ScienceDirect Topics
The concentrate grind at a P 80 of 10 μm contained 65% gangue minerals, 23% pyrrhotite, 2.2% pyrite, 9.6% arsenopyrite, 75.5 g/t Au, and 5.0 g/t Ag. Gold was present as native gold and electrum. A test conducted at 2000 ppm NaCN and pH 11.0 produced 97.0% extraction of gold in 72 h. It was found that an efficient leaching required only 3–5 ppm DO.
