Answer 2

the fundamentals of matte smelting and the influence of process variables. Matte smelting is the most common way of smelting copper–iron sulfur concentrates. The primary purpose of matte smelting is to turn the sulfide minerals in solid copper concentrate into three products: molten matte, molten slag, and offgas. This is done by reacting them with oxygen. Smelting strategy involves a series of trade-offs and the most significant is that between matte grade and recovery. The industrial matte smelting equipment and procedures vary, but all smelting processes have a common sequence of events. It entails heating, oxidizing, and fluxing the concentrate at high temperatures, approximately at 1250℃. Matte smelting oxidizes most of the iron and sulfur in its input concentrates. Total oxidation of iron and sulfur would not only produce molten copper, but also result in large copper oxide losses in slag. The chapter also provides compositions of industrial concentrates, fluxes, mattes, slags, and dusts for various matte smelting processes.
