What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brassyellow 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.

These separators utilize strong magnetic fields to separate iron minerals from lowergrade nonmagnetic ores. The efficiency of this separation process is largely determined by the Fe content, or iron content, of the ore. Highgrade iron ores, with a higher Fe content, are more valuable and therefore more profitable to process. Related News

In total, 165 scenarios were simulated. When the mills charge comprising 60% of small balls and 40% of big balls, mill speed has the greatest influence on power consumption. When the mill charge is more homogeneous size, the effect of ball segregation is less and so the power consumption of the mill will be less affected.
