The matte, which is produced in the smelter, contains 30–70% copper (depending on the process used and the operating philosophy of the smelter), primarily as copper sulfide, as well as iron sulfide.
Matte is transferred to Converters for further processing. The Copper Matte is converted into Blister Copper in the Pierce Smith Converter in two stages.In the first stage, called Slag Blow, most of the iron and a small quantity of sulphur are oxidised and removed. In the second stage, called Copper Blow, sulphur is removed to get Blister Copper.
