Extracting metals with charcoal. If the carbon is more reactive than the metal it will remove the oxygen from the metal oxide and leave traces of the metal in the reaction vessel. The first experiment uses lead (II) oxide; the second modifies the technique slightly and uses copper (II) oxide.

4a. The extraction of copper from copper ores and its purification by electrolysis. Copper is well below carbon (less reactive) and so can be displaced by carbon from its compounds eg copper oxides or sulfides. However, in practice, modern copper smelters can actually manage the extraction without using carbon (coke) and then electrolysis is usually used to purify the impure copper from the smelter.

Extraction of Copper. A way of extracting the copper from the minerals from underground was eventually discovered. It involved "roasting" the sulphide minerals in the air, which converted the elements to their oxides: CuS (s) + (g) CuO (s) + SO2 (g) The metal oxide can then be reduced to just the metal.

Copper ore is a vein of green copper carbonate embedded in granite. Gains malachite chunks when mined. Be careful, because certain ores require special tools for successful mining of the mineral. If improper tools are used, the mineral is lost. Further processing in the furnace is required to extract pure copper from the carbonate.

The ability to extract copper from ore bodies was welldeveloped by 3000 BC and critical to the growing use of copper and copper alloys. Lake Van, in presentday Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths who used the metal to produce pots, trays, saucers, and drinking vessels.
