  • Technology of Sulphidisation and Flotation of Non-Sulphide

    The paper deals with the effect of sodium polysulphides in chrysocolla . Activity of elementary sulphur adsorption on the mineral surface is discussed. The mechanism of polysulphide action in the process of sulphidisation and formation of sulphur on the mineral surface is proposed. Sodium pentasulphide is shown to be the most effective modifier of chrysocolla

  • Sulphide Gold Ore Treatment by Leaching and Flotation Process

    Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

  • Tailings

    Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

  • The Influence of Pulp Potential in Sulphide Flotation - AusIMM

    The influence of pulp potential on the behaviour of sulphide minerals in laboratory batch tests is discussed in terms of self-induced flota- tion, collector-induced , and depression.’ Assuming that the pulp poten- tial is controlled by the same factors that determine the genuine redox poten- tial, an attempt is made to interpret the
