Oxidized species and chalcocite (Schippers and Sand, 1999) can be easily leached with low concentration acid medium extracting copper from the ore. Total copper concentration in the samples (%) was higher than the average value reported for the reservoir (Danielli and Giusiano, 1992).
Mar 01, 2017· The recovery of oxide copper minerals from a complex copper ore by sulphidisation Corin, ; Kalichini, M.; O'Connor, ; Simukanga, S. 00:00:00 •In all cases the addition of NaHS resulted in higher recoveries of Cu.•Using the CPS method resulted in an increase in Cu recovery but a decrease in grades.•Slug addition at 500g/t resulted in a slightly higher Cu recoveries than at 250g/t.
only two ore types: oxide and sulphide. All transitional ores mined during the period leading up to 2009 was stockpiled. The treatment of the minerologically complex transitional ores through a third train commenced in June 2009, but entailed numerous metallurgical challenges. This transitional ore (called 'mixed ore') could not
Apr 13, 1982· In accordance with the present invention, the recovery of copper from oxidized copper deposits containing atacamite/paratacamite is improved by utilizing a particular combination of collectors or flotation agents when conditioning a slurry of copper ore.
bility and recovery of the oxide copper minerals. That the industry would benefit greatly, ifmore of the oxide minerals were recovered, is evident when the large tonnages treated are considered. Consequently there is need for an improved method of recovering the oxidized copper minerals associated with the sulphide copper ores.
This object is achieved in that in the method of recovery sulfiding smelting of oxidized Nickel ores, including blending of ore with sulfidization, fluxes, agglomeration of all or part of the charge and smelting to produce Nickel matte and slag, according to the invention at a stage of blending ore as sulfidization use of sulfidemetal alloy containing 511% Nickel, 1025 sulfur, iron rest, when the mass ratio of Nickel .
the leaching process of copper oxide ore. Moreover, an experimental design technique, Response Surface Method (RSM), is employed to model, optimize, and evaluate the e ects and interactions of the in uential parameters on recovery of copper. 2. Experimental descriptions Materials Copper oxide ore was collected from the Fariman
Practical aspects of oxide copper recovery with alkyl hydroxamates Our studies on a wide variety of copper ores from around the world have shown that alkyl hydroxamates will recover most of the "floatable" oxide copper minerals from an ore.
Flotation experiment research on a polymetallic sulfide ore of Cu, Pb, and Zn in Shanxi province ... The polymetallic sulfide ore of copper, lead, and zinc is widely found all over the world and is often associated with ... The recovery of copper and lead in the mixed concentrate improved with .
Solvent Extraction / Electrowinning is the most dominant leaching process used today in the recovery of copper from chemical solutions. As the name suggests the method involves two major stages: Solvent Extraction the process by which copper ions are leached or otherwise extracted from the raw ore using chemical agents.
best performance. Bench flotation was performed on three different ores, a Mexican fluorite ore, a Peruvian copper ore, and Morenci copper ore. With the addition of Tupasol ATO, the recovery and grade of the fluorite concentrate was seen to increase. Tupafin ATO was shown to provide a
2 lists the names of the mines that produce copper by the bioleaching technique [12]. Bacterial oxidation of sulfide ores for copper recovery has been carried out in Spain, Sweden, Germany, China, and other countries for centuries without knowing its cause. More than .
Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process .It is a high technological enterprise .
According to these results, it was observed that enargite in the mixed ore can first be recovered at pH 4 followed by chalcopyrite recovery at pH 8. As content in both chalcopy rite concentrate and final tailings was reduced to below %. The enargite concentrate can be treated separately for As removal.
