    Copper is extracted from copper pyrites. After roasting the ore is mixed with silica and coke and then smelted in a blast furnace. The matte obtained from the blast furnace is charged into a silica lined converter. Some silica is also added and a hot air blast is thrown into the mixture to obtain blister copper which is purified by.

    Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step mineral processing is to liberate the copper minerals and remove waste constituents—such as alumina limestone pyrite and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

    Jan 01 2016 The simplest method of copper extraction using sulfuric acid is applicable only to ores containing oxidized copper minerals such as malachite azurite and chrysocolla. Generally these processes are uneconomic in treating low-grade copper ores particularly sulfide ores due to the high reagent consumption neutralization required before.
