The process known as flash smelting combines the benefits of flash roasting and matte smelting. The flash smelting of galena concentrate produces lead while those of chalcopyrite and pentlandite concentrates produce high-grade matte. Smelting happens to be one of the main steps in the extraction of metals from sulfide and oxide minerals by adopting the pyrometallurgical route. During smelting, constituents present in the charge in molten state separate into two immiscible liquid layers, namely, liquid matte or metal and liquid slag. The primary objective of matte smelting is to produce a liquid matte containing almost all the copper present in the charge and a slag with least copper. The physical chemistry of the matte-slag systems is controlled by iron, copper, sulfur, oxygen and their sulfides and oxides.Read More
