Iron ores with a high content of impurities, such as sulfur, have been processed pyrrhotite fe xs is a kind of common sulde which exists in magnetite ore as an associated mineral with little industrial value the contamination of sulfur emanating from pyrrhotite in magnetite concentrates has been a problem in iron ore smelting process
Grade copper ore may be only one quarter of one percent the gold content of a good grade gold ore may be only a few onehundredths of a percent therefore, the next step in mining is grinding or milling the ore and separating the relatively small quantities of metal from the nonmetallic material of the ore in a process called .
