Copper Smelting Chemistry Tutorial

Smelting with Fluxes*: converts the calcine to matte (a mixture of copper sulfides and iron sulfides) Calcine is heated to over 1200oC with fluxes such as silica (SiO2) and limestone (CaCO3). Calcine melts and its compounds react with the fluxes.

2018-01-11  Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

Copper mining. Chemical reactions.

Smelting with fluxes: The calcine is heated to over 1200 °C with fluxes such as silica and limestone. The calcine melts and reacts with the fluxes. Some impurities form a slag which floats on the surface of the liquid (like oil on water) and is easily removed. For example: This is very similar to the removal of impurities in the blast furnace. The liquid left is a mixture of copper sulphides ...

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
