What is 'copper matte' ?
Advertisements
उत्तर
During extraction of copper from cuprous oxide in a reverberatory furnace, cuprous oxide is mixed with silica and heated. This leads to separation of iron oxide as iron silicate (slag) and the copper obtained after this procedure is known as copper matte. It contains Cu2S and FeS. It is then put in a silica-lined converter to remove the remaining FeO and FeS present in the matte as slag (FeSiO3).
