Copper extraction - Wikipedia

The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. ... Therefore, further stages of processing (converting and fire refining) are required. The following subsections briefly describe some of the processes used in matte smelting. Reverberatory furnace smelting. Reverberatory furnaces are long furnaces can treat wet, dry or roasted concentrate.

copper extraction and purification - chemguide

The process. The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is
