Copper - Principal compounds | Britannica

Copper(I) (cuprous) compounds are all diamagnetic and, with few exceptions, colourless. Among the important industrial compounds of copper(I) are cuprous oxide (Cu2O), cuprous chloride (Cu2Cl2), and cuprous sulfide (Cu2S). Cuprous oxide is a red or reddish brown crystal or powder that occurs in nature as the mineral cuprite.

Copper Mining and Extraction Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.
