A copper smelting plant in Chile is examined as a case study. The smelting process is one of the most important and critical phases in any mineral processing system, especially in copper plants. 1 The selected mining process is divided into four main subsystems: drying, concentrate fusion, conversion, and refining.
Copper concentrate (Cu:22-29 %, S: 27-32%, Fe: 22-27%) is fed through lance pipe with oxygen enriched air into the smelting furnace then oxidized and melted by exothermic reaction to form molten mixture of matte (Cu: 68%) and slag. The matte is separated from slag by difference of specific gravity in the slag cleaning furnace.
