Copper Leaching Method 911 Metallurgist
When the copper to be extracted is found mineralized as a sulphide the use of sulphuric acid as lixiviant necessitates breaking up the sulphur combinations by roasting in order that the metal can be brought into soluble form This operation, however, instead of being a drawback, presents advantages This research was aimed to investigate the leaching behavior of zinc and copper from a porcelain stone tailings sample using RSMCCD modeling The synergetic and individual effects of five main factors including liquid/solid ratio, sulfuric acid concentration, agitation speed, leaching time, and temperature were examined on the recoveries of zinc and copper For this purpose, two 2F1 models Leaching of copper and zinc from the tailings sample Tailings characteristics can vary greatly and are dependent on the ore mineralogy together with the physical and chemical processes used to extract the economic product Ritcey (1989) reported that tailings of the same type may possess different mineralogy and therefore will have different physical and chemical characteristicsTailingsfo What Are Tailings?
