The attractions of copper SX/EW are now well known – it is highly selective, can treat a wide range of copper concentrations, produces high purity cathode at site, is suitable for both large and ...
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 that integrated research, manufacture, sales and service . The company has multiple subsidiaries such as Mineral ...
Jul 17, 2014 leaching, achieving an efficiency in the flotation concentration stage higher than 75%. Based on the performed experimental results, the flow sheet for processing of the mixed oxidesulfide copper ore is proposed. Keywords: oxide–sulfide copper ore, leaching, flotation, increase of copper recovery.
The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
paper. The results of chloride leaching of silver and lead from solid residue after nonoxidative leaching followed by atmospheric leaching of the Lubin flotation copper concentrates in oxygenated sulfuric acid and in the presence of Fe(III) are presented.
In this study, the leaching characteristics of copper flotation waste have been evaluated by the Toxicity Characteristic Leaching Procedure (TCLP), Synthetic Precipitation Leaching Procedure (SPLP), Extraction Procedure (EP Tox), and Field Leach Test (FLT) tests methods. The adsorption capacities and adsorption efficiencies were determined.

Abstract The leaching behavior of a copper flotation concentrate was investigated using ammonium persulfate (APS) in an autoclave system. The decomposition products of APS, active oxygen, and acidic medium were used to extract metals from the concentrate.
A roastingleaching technique, in which the residue for firststage leaching was roasted between 360 deg and 500 deg c before a second leaching with h2so4, solubilized 98 pct of the copper. The three leaching methods yielded highgrade PGM residues containing more than 98 pct of the PGM in the matte.

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan, Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.
Oxide copper ore, lowgrade copper sulfide overburden, and other coppercontaining materials are stacked into a heap. Leach solution (pH approximately 2) is sprinkled or flooded on top of the heap and percolates through. The leach solution containing the dissolved metal eventually flows out of the heap into a collection pond.
flotation to recover entrained copper contents. This technique produces a flotation concentrate copper grade of approximately 25 to 30% with copper recoveries of between 60 and 70%. However, the ... leaching of copper from copper slag is shown in Figure 1. RESULTS AND DISCUSSION
the part of cooper oxide either by leaching of grinded ore prior the flotation or by leaching the flotation tailing coming out from the concentrator. Direct leaching process of copper oxides or complex ores attracts considerable scientific and engineering attention, which plays an important role in the sustainable development of copper industry.
Hydrometallurgical Production of Copper From Flotation Concentrates By J. R. Cobble, C. E. Jordan, and D. A. Rice UNITED STATES DEPARTMENT OF THE INTERIOR Bruce Babbitt, Secretary BUREAU OF MINES This report is based upon research conducted under an agreement between the University of Alabama and the Bureau of Mines.
Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation. Also for some copper ore it is combined by both oxide copper ore and sulfide copper ore, after processing test combined processing technologies can also be adopted to extract copper.
