flotation copper ore

Apr 13, 2016 Flowsheet for treatment of Copper Sulfide ores rich in minerals such as chalcopyrite with gold and silver as well as arsenopyrite. The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper. This flowsheet, though simple, is adequate for tonnages of 100 to 500 tons or

    US3827557A - Method of copper sulfide ore flotation

    A novel flotation promoter used in the concentration of copper bearing ores for the efficient selective flotation of copper values, including chalcopyrite, with suppression of iron pyrites; the promoter comprising a sodium sulfate of an aliphatic hydrocarbon having a carbon chain in excess of 12 carbons and chemically combined with at least one mole of the C2-C3 alkylene oxides

    Flotation of oxide copper ore with sodium oleate from

    The flotation of oxide copper ore with sodium oleate was investigated to determine the optimum pH and dosages of chemical reagents. From the mineralogical analysis using X-ray diffraction, malachite was the major mineral and the gangue minerals were mostly silicates such as quartz and kaolinite. As a result this ore was characterized as oxide

    Effect of Desliming on Flotation Response of Kansanshi

    The Kansanshi mixed copper sulfide-oxide ore contains significant proportions of fine material manifesting in a variety of processing challenges. This paper presents the work which was carried out to evaluate the efficacy of desliming in improving the flotation response of the ore. Two modes of desliming were investigated, namely; sieving and elutriation after which the deslimed material was
