Copper extraction - Wikipedia

The Old Copper Complex in North America has been radiometrically dated to 9500 BP—i.e., about 7480 BCE—making it one of the oldest known examples of copper extraction in the world. The earliest evidence of cold-hammering of native copper comes from the excavation at Çayönü Tepesi in eastern Anatolia, which dates between 7200 to 6600 BCE. Among the various items considered to be votive ...

Abstract. The modes of action of the commercial solvent extractants used in extractive hydrometallurgy are classified according to whether the recovery process involves the transport of metal cations, M n +, metalate anions, MX x n −, or metal salts, MX x into a water-immiscible solvent. Well-established principles of coordination chemistry provide an explanation for the remarkable strengths ...

To control the aqueous solution pH, the copper solvent extraction was conducted by addition of NaOH solution into copper chloride solution. The extraction reaction is expressed as: (4)2HR (org) + CuCl2 + 2 NaOH = CuR2(org) + 2 NaCl + 2 H2O With increasing copper extraction, the CuCl 2 concentration decreased and the NaCl concentration increased.

However, by far the greatest extension in the use of copper resulted from Michael Faraday's discovery of electromagnetic induction in 1831 and the way that the effect could be used to generate electricity. The same principle was used to develop electric motors. The electric lamp was invented by Sir Joseph Swan in 1860 and brought to a commercial design by Thomas Edison in 1879.

The principle behind solvent extraction is extremely basic. The goal is to use a liquid ( solvent) to dissolve ( solvate) a target molecule or group of compounds ( solute) and to wash them out of the solid plant material. The solvent is then separated from the solute in order to concentrate the solute.
