Purification of low grade molybdenite by acid leaching processes
High purity(>98%) molybdenum disulfide from molybdenite is an excellent solid lubricant,which can be used in automobile ,aerospace and military field.Molybdenite is the most widely used concentrate in the production of MoS2.Molybdenite usually contains some sulfide minerals such as covellite (CuS),pyrite (FeS2) and chalcopyrite (CuFeS2),and some other impurities like quartz (SiO2).The purity of molybdenum disulfide includes a series of refining step in order to produce high grade molybdenite concentrate.The removal of copper,silica and iron impurities from low grade molybdenite concentrate is very important.Ferric chloride solution containing ferrous chloride and hydrochloric acid is a strong kind of oxidizing lixiviant which is capable of leaching copper minerals such as covellite,chalcopyrite,chalcocite,ect.Hydrofluoric acid is best know to the public for its ability to dissolve silica.Sulfur is soluble in
