Typical compositions of copper concentrate, matte, and blister copper

The document outlines the metallurgy of copper, detailing key ores and the extraction process, which includes concentration, roasting, smelting, and bessemerization. It explains that blister copper, resulting from these processes, is about 99% pure and contains various impurities. Finally, the refining of blister copper is achieved through electrolysis to obtain 100% pure copper. - Download as.. Direct to blister copper process is the technology that is used to directly produce copper by using copper sulfide concentrate in a single equipment (Fig. 1). Some special copper ores, e.g., chalcocite (Cu2S) and bornite (Cu5FeS4), have high copper content and low iron content, the grade of their concentrate is similar to that of copper matte, and only a small volume of slag is generated.

Discover the significance of Blister Copper in Extractive Metallurgy, its production process, and applications in various industries.. The figure shown below schematically describes the Mitsubishi Process, illustrating its sequence of continuous and controlled smelting of copper concentrates, coal, and flux; the separation of copper matte and discard slag; the continuous conversion of copper matte to blister copper; and finally, the continuous delivery of blister copper to the anode furnaces.
