Copper Leaching Method 911 Metallurgist

2019-4-19  Extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration, smelting, and refining, and experimental data tend to confirm this opinion. At the Butte-Duluth plant, which is handling in excess of 100 tons of oxidized ore daily, the copper is said to cost $0.085 per pound.

Leaching of copper concentrates University of Arizona

2020-4-2  copper oxides have been in common use for some time. Prior to the development of the Sherritt-Gordon process for nickel and cobalt in which copper is recovered as high grade copper sulfide, copper sulfides were economically recovered in a hydrometallurgical process only during the leaching of waste dumps. .

Leaching of Copper Sulphides SAIMM

2016-6-8  Outotec’s copper chloride leaching process is carried out in atmospheric leach reactors with cupric ions, Cu(II), in a chloride media at a pH between 2 and 2.8. The leach conditions are suitable for the leaching of all copper sulphide minerals, such as chalcopyrite, bornite, chalcocite, covellite and digenite (Valkama, 2013). These leach conditions have delivered high recoveries of copper and silver (95–98% and 93–96%, respectively) in batch tests and pilot runs. Chloride from sodium chloride enables the leaching reactions but it is not consumed in them and sulphuric acid is used as a makeup acid. Because of the nature of the leaching solution and the subsequent SX, neither chemical has stringent purity requirements. Silver and gold can be recovered also if they are present in the feed. As a result, the technology is suited to a wide variety of copper-containing

Limits of the CIL circuit in copper–gold plants

2014-1-1  The leaching of flotation tailings in copper–gold plants (e.g., Telfer) is difficult. • The occlusion and fine grain size of gold attribute to the low leach recovery. • Fine grinding of the pyrite concentrate increases gold recovery from leach. • Fine grinding increases released copper ions

Copper recovery using leach/solvent extraction

2009-8-27  low quality copper from the leach solution on scrap iron, was practiced on oxide ore that was too low-grade for vat leaching, or low grade sulphide ore that had to be mined in order to expose the underlying high grade sulfide ore. Copper recovered from leaching low grade copper ores was considered a bonus and little effort had been made to fully
