Mineral deposit Flowing surface water When mineral grains of different density are moved by flowing water, the less dense grains will be most rapidly moved, and a separation of high density and low density grains can be effected. Mineral deposits formed as a result of gravity separation based on density are called placer deposits. For effective concentration, placer minerals must not only

2018 10 4ensp;0183;ensp;In geology, eluvium or eluvial deposits are those geological deposits and soils that are derived by in situ weathering or weathering plus gravitational movement or accumulation.. The process of removal of materials from geological or soil horizons is called eluviation or leaching.There is a difference in the usage of this term in geology and soil science.
Secondary enrichment. An especially important class of residual deposit is formed by both the removal of valueless material in solution and the solution and redeposition of valuable ore minerals.

Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.
