Blowing Rotary Kiln output blister send fire refining processing, smelting converter slag and dust return to the workshop or individual treatment, flue gas is used acid. The purpose of the Rotary kiln is blowing ice into blister copper.Blowing periodic Rotary kiln operations, each cycle is divided into two phases, i.e. slag and made of blister copper phase.Smelting process, four kinds of devices have their own characteristics, but the vast majority are the product of smelting matte.Smelting, when the charge contains sufficient sulfur at a high temperature since copper is greater than the affinity of iron sulfide, iron and copper is greater than the affinity for oxygen, so it can follow the reaction of the copper sulfide: copper present a variety of methods are basically is the first output matte, matte send converter blowing Make blister.
