Botswana Slag Processing Copper Iron

Copper matte

Copper matte

The process utilizes an oxidizing agent, such as air or oxygen gas, to oxidize iron sulfide into iron oxides in the form of slag, leaving behind a matte phase with a high concentration of copper. Silica is used in matte smelting to form molten ironsilie slag with the iron oxides produced in Reaction 1: (2)

Copper Smelting

 · The matte, about 45 to 55 percent copper and the remainder iron silie slag, is formed in a very fast, almost instantaneous reaction; hence the name "flash smelting.". The matte sinks through the lighter slag layer and flows down the. inclined crucible. Conversion to copper proceeds in .

Copper slag was characterized and processed. The pyrometallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440°C) helped recover a majority of the metal values (, Fe, Cu and Mo) into the ironrich alloy product which can be a feed material for steel making.
