    2021-2-23 · A pot made out of copper. Matte is then poured into a converter where it reacts with air lime and silica to separate the copper from iron slag. The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and purification to remove any remaining impurities.

    1246 Points. Silica (SiO2) is used in the processes of smelting of copper pyrite (CuFeS2) ore and in conversion of produced copper matte (refined copper sulfide) into a crude metal as a flux (purifying agent). It reacts with solid impurities such as iron oxide and forms a liquid slag with density smaller than the copper matte.
