gravity concentration sink floatation

density separation

density separation is based on the fact that different minerals have different densities thus if a mixture of minerals with different densities can be placed in a liquid with an intermediate density the grains with densities less than that of the liquid will float and grains with densities greater than the liquid will sink typical
