The Smelting of Copper The first written account of the processes of smelting and refining of copper is to be found in the 12th century1 On smelting Copper is engendered in the earth When a vein of which is found it is acquired with the greatest labour by digging and breaking It is a stone ofApr 14 32 The resulting copper from this step is known as blister copper Blister copper undergoes further firing and purification to remove any remaining impuriti One of the main side effects of the copper smelting process is the production of waste Refining copper results in three and a half times as much waste as the amount of copper produced
