Leaching process for copper concentrates The
A method of leaching copper from copper sulphidecontaining concentrates, such as chalcopyrite, includes using pyrite as a catalyst for ferric reduction in order to eliminate passivation of the chalcopyrite surface, the process being carried out under conditions whereby the pyrite is not materially oxidized, for example by maintaining the operating solution potential at a suitable levelA selective acid leaching process was then used to recover the copper content of the residue after filtration In the second stage, an additional 1 N of sulphuric acid was added to the suspension in the selective leaching process, and the pH value was controlled at 1520Selective leaching process for the recovery of copper 2 天前 Generally heap leaching process is employed in copper leaching process but sometimes a combination of heap leaching and in situ leaching processes are used The solution (Sulphate/Fe 3 solution) is sprinkled over the heap which percolates through the ore and collects at the bottom pitBioleaching: Introduction, Methods, Application,
Leaching Process Examples, Types, Advantages and
The process of leaching is used to extract the substances from the solids This process is carried out when the given substance is allowed to dissolve in a liquid It is carried out either through a natural process or industrially In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid The first process, vat leaching of highgrade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost In Copper recovery using leach/solvent extraction the transport and enable the leaching of copper This is done by mixing the Calcine with recycled liquid from the electrowinning section, socalled anolyte: the anolyte is assumed to consist of copper sulfate CuSO 4 and sulfuric acid H 2SO 4 dissolved in water The Calcine is slurried in two tanks, with volumes V(1) s and V(2)MODELING OF AN INDUSTRIAL COPPER LEACHING AND

The "GallCopper Process" was recorded as being used during the Song Dynasty (9601271AD) Copper was precipitated from solution by dipping iron into the blue vitriol solution a process identified as early as 150 BC in China 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date copper L/SX/EW operation, the Bluebird plan of Ranchers Exploration and Development Corporation, came on line1 Copper recovery by L/SX/EX in 1968 In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid The first process, vat leaching of highgrade copper oxide ore followed by EW ofCopper recovery using leach/solvent extraction MODELING OF AN INDUSTRIAL COPPER LEACHING AND ELECTROWINNING PROCESS, WITH VALIDATION AGAINST EXPERIMENTAL DATA Bernt Lie1, Tor Anders Hauge2 1Telemark University College, PO Box 203, 3901 Porsgrunn, Norway 2Xstrata Nikkelverk, Kristiansand, Norway , ELING OF AN INDUSTRIAL COPPER LEACHING AND
