Copper is mainly extracted from the sulphide oreCu2 S by the self reduction process. More silica is added which forms more slag with the iron oxide.
However, to extract the copper from copper ores smelting was required. Typically, ores are impure and require a flux to separate the metal from the slag. in powder form it is possible that accidentally putting Malachite powder on the coals
Typical copper ores contain from 0.5% Cu to 1 or 2% Cu. About 80% of the worlds copper-from-ore is produced by concentrationsmelting refining of sulfide ores. . Concentrate feed is dried and blown into the matte-slag bath through
They must be concentrated to ~30% Cu before smelting. The universal . When this happens, the Cu2O dissolves in the slag generated during coppermaking.
Smelting of nickel sulfide ores yields a matte in which nickel and copper make of the iron, react with the flux and form a light, fluid layer of slag over the matte.
Slag: Slag,, by-product formed in smelting, welding, and other metallurgical and combustion processes from impurities in the metals or ores being treated. Slag consists molten copper. copper processing: Roasting, smelting, and converting.
