  • New breakthrough copper recovery process developed by

    In the FLSmidth ROL process, a simple way has been found to leach copper sulphide concentrates, with chalcopyrite as the predominant copper-bearing mineral, at 85 to 95°C and under atmospheric pressure.

  • Copper Chloride Leaching Process Outotec

    Our copper chloride leaching process utilizes our highly effective atmospheric chloride leaching technology, including gold and silver recovery. We have coupled this with world-renowned VSF solvent extraction and electrowinning technology to make a process that is especially effective with low-grade and impure copper feed materials.

(Courtesy of BHP Billiton.) Copper ore is loaded into trucks. In some mines these trucks have no driver. (Courtesy of Codelco.) This truck carrying copper

  • COPPER EXTRACTION BY BIO-LEACHING OF FLOTATION

    The sulphide concentrate used in the experiments is the result of the copper sulphide flotation process from a primary ore (underground mining). The copper sulphide flotation concentrate under study contains about 30% of bornite (Cu5FeS4) and 70% of chalcopyrite (CuFeS2). The particle size

  • Leaching of copper(I) sulphide by sulphuric acid solution

    01/07/2003· Sullivan (1933) studied the leaching processes of copper sulphides by acidified ferric sulphate solutions. He showed that chalcocite (Cu 2 S) dissolves in a two-stage process with covellite (CuS) as the solid product formed at the end of the first stage. In the second stage, the process occurs through the formation of elemental sulphur.

  • Application of SART to Heap Leaching of Gold-Copper

    Ores in which the oxidation weathering processes have been pronounced with high removal of sulphur and copper units from the original sulphides result in low levels of residual copper and sulphur. This residual copper may be in the form of oxide and/or hydrolyzed copper minerals such as

  • NEW COPPER LEACH TECHNOLOGY Miningreview

    The Galvanox technology is a novel atmospheric leaching process which offers several potential advantages over existing copper-leach processes for primary copper sulphides. As it is selective for the primary sulphide mineral chalcopyrite over pyrite, it is applicable to low grade or bulk concentrates. Copper recoveries of 98 % or greater have been achieved in test work under controlled

  • First Chalcopyrite Copper Concentrate Leaching using

    the region and wanted to prove up the concept of sulphide copper leaching at a commercial scale using the Albion Process TM. A very cheap retrofit was undertaken on the existing oxide leach circuit and then fed a predominantly chalcopyrite/bornite concentrate (28- 30% Cu). After a very short commissioning stage of around ~6 weeks, it achieved recoveries in excesses of 99% out of the leach
