  • How a Thickener Works Mineral Processing & Metallurgy

    Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were

  • Precipitate Gold Mercury with Electricity

    The state of efficiency of the mercury surface has a good deal to do with the current density. The better the surface of mercury, the higher current density can be used, without forming gold that will not amalgamate. Thus, when running with .6 amperes per square foot, all the gold deposited was amalgamated; but, on ceasing to revolve the barrel
