  • Procedure Residual Copper Soluble Analysis

    Sequential copper analyses performed on pre-leaching head and post-leaching tail samples from metallurgical test work can provide valuable information relating to the percent extraction or leaching efficiency of each of the mineralogical types present in the sample and aid in selection of the most appropriate leaching parameters...

    Copper extraction from primary copper sulfide ore from a typical porphyry copper deposit from Antofagasta, Chile, was investigated after leaching with a chloride-ferrous media at two temperatur The study focused on whether this chemical leaching system could be applied at an industrial scale Leaching tests were conducted in columns loaded with approximately 50 kg of agglomerated ore; the ....

  • Decommissioning of Copper Heap

    Jul 06, 2004· Acid heap leaching is widely applied around the world for the purpose of recovering copper from copper oxide or Nevertheless, environmental issues associated with the large volumes of spent ore left by leaching have received only limited attention from the mining and research communiti At sites with a positive water balance, seepage ,...

  • Leaching of Primary Copper Sulfide Ore in Chloride

    Abstract: Copper extraction from primary copper sulfide ore from a typical porphyry copper deposit from Antofagasta, Chile, was investigated after leaching with a chloride-ferrous media at two temperatur The study focused on whether this chemical leaching system could be ,...

  • US20160258036A1

    A method of leaching copper from a heap of ore that includes at least one resting step followed by an irrigation step, wherein, during the irrigation step a leach solution that contains chloride ions is applied to the ore at a higher rate than during the resting step...

  • One Character Effects on Copper Heap Leach Management

    Copper heap leaching involves both the simultaneous and sequential leaching of very large tonnages of ore over long periods of time It is not unusual to be leaching three or four million tonnes over periods of 12 to 18 months As a consequenc...

  • Facile and Cost

    The recovery of copper (Cu 0) from waste printed circuit boards (WPCBs) is a great challenge as a result of its heterogeneous structural properties, with a mixture of metals, epoxy resin, and fiberglassIn this study, a three-step sequential process, including mechanochemical processing, water leaching, and recrystallization, for Cu 0 recovery from WPCB powder is reported...

  • Sequential Copper Analysis Methods

    I've been looking into several different deposits where sequential copper analysis are carried out to estimate the amount of the total copper in phases such oxides, secondary sulphides, silicates and even one case minerals soluble by water However, there seems to a variety of methods and conditions...
