The minerals and waste rock are separated at the mill using . The ore slurry from the grinding mills is mixed with milk of lime simply water and ground-up limestone to give a basic pH, pine oil yes, it comes from trees -- a by-product of paper mills to make bubbles, an alcohol to strengthen the bubbles, and a

  • Froth flotation

    For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector. The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not wanted

  • Separation efficiency improvement of a low grade copper

    configuration is sequential , where bearing minerals are recovered to a saleable concentrate, followed by re-activation and of the which is leached with cyanide to recover gold. Both trains produce a concentrate with significant quantities of

    Electronic the -activated surfaces [45,146,153,159,162]. structure and band structure studies on four types of including It was reported that, during conditioning of at pH 7, if perfect, Co-substituted, As-substituted, and intercrystalline Au equal dosage of xanthate collector and are used, the was performed

  • 60 Centuries of Copper: The Flotation Process

    In the case of minerals, the particles adhere to this , which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making highly selective in skilled hands

  • flotation method copper

    The of the prior art copper, the original ore was pulverized ore is suspended in water, wherein the added inhibitor to inhibit the of Pb, bubbles are generated by blowing air it makes levitate on the liquid surface by adhering particles in the bubble

  • Surface chemistry of activation of lime-depressed pyrite

    The depression of by lime is attributed to the surface formation of CaOH2, CaSO4 and FeOH3 as determined by XPS analysis. Xanthate tests show that oxalic acid and other

    Make a bulk float of all sulfides, followed by selective separation of the valuable minerals from the pyrite which is then sent to tailings. Make a selective float of the valuable minerals at the beginning, depressing the pyrite at the same time by use of a high-lime condition in the flotation

  • EP0568672B1 - Flotation separation of arsenopyrite from

    The use of sulfur dioxide for depressing sphalerite ZnS during the flotation of pyrite is well established. Similarly, Canadian patent 1,238,430 teaches the use of sulfur dioxide to separate
