Other uses of flotation include biochemical and ...

  • Copper Mining And Processing From Mine To Copper Plate

    The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore -0.5 mm going to froth flotation cells for recovery of copper.

  • Rougher Flotation Of Copper Sulphide Ore Using Biosolids

    Nov 01, 2011 Rougher flotation results for the concentration of a copper sulphide ore in a Denver cell with biosolids or a salt of humic acids as both collector and frother indicate that these materials have potential to substitute conventional chemical collectors and frothers used in the industrial flotation of sulphide minerals in Chile.

  • Concentrating Resolution Copper

    The technique all begins with a wet grinding process that turns the crushed ore into a slurry and transports it to flotation cells. When mixed with water, reagents, and air, the copper minerals produce a bubbly froth. The bubbles with copper are skimmed and filtered to produce copper concentrate. The concentrate, which contains about 29-31 ...

  • The Interaction Between Cations In Saline Water And

    Sep 10, 2020 In this study, the effect of cations, Na and Mg2, in saline water on copper flotation in the presence of calcium bentonite was investigated. It was found that as the concentration of NaCl was increased, the copper recovery initially decreased and then increased to above 99, while the copper grade initially increased and then decreased. In contrast, as the concentration of MgCl2 was ...

  • Estimation And Improvement Of Recovery Of Low Grade Copper

    Copper oxide ore is an important copper ore resource. For a certain copper oxide ore in Yunnan, China, experiments have been conducted on the grinding fineness, collector dosage, sodium sulfide dosage, inhibitor dosage, and activator dosage. The results showed that, by controlling the above conditions, better sulfide flotation indices of copper oxide ore are obtained. Additionally, ammonium ...
