Froth flotation process for the concentration of sulphide ores

History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for

    Mar 27, 2016 The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which

    Froth floatation process is used to extract the metals in which the particles of ore are wetted by oil and particles of gangue are wetted by water. This is done to remove gangue particles from sulphide ores. A suspension of powdered ore is made in water and small quantities of collectors and stabilizers are added to it. Collectors are adsorbed on the mineral particles and
