  • Gold Gravity Concentration Mineral Processing & Metallurgy

    The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal is

    GRAVITY CONCENTRATION. The most widely employed processes of gravity concentration depend on the behavior of mineral particles in water (dry processes also have their place) and take advantage of the difference in the speed with which minerals of varying size and density fall in still or moving water; or of the difference in the resistance that
