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.
General Application. Iron pyrite increases thermal conductivity when used as an active filler in pressed, resin-bonded grinding and cut-off wheels, brake pads, and other friction applications. This increase in thermal conductivity improves the durability of organic bonded abrasives. Balances the hardness/friction coefficient of brake pads.
The ultra-fine-grinding and resin-in-pulp with pH value of 10 are used to extract gold from pyrite roster cinder. During leaching process, aluminium oxide ball is used as stirring medium, hydrogen peroxide as leaching agent and sodium hexametaphosphate as grinding agent. With AM-2σ resin as absorber and sulfocarbamide as eluent, gold is recovered from cyanide pulp of pyrite roster …

Ball milling produced a greater size spread between the coals in stages of grinding than did the Hardgrove mill. ... Stage grinding improved pyrite removal by about 30 pct and increased the reject portion from 12 pct to 18 pct.
with coal feeds obtained by either dry grinding or wet grinding. 1-1 Therefore, the effect of different grinding methods on the separation of coal from pyrite from other ash forming minerals is not clear from these studies. Miller and Guzzo~ have compared the effect of dry and wet grinding methods for deep cleaning ultrafine coal by flotation.
