Placer deposits - CONCENTRATION OF MINERALS

Current and future processing schemes of placer minerals are included usually several ways of gravity separation of minerals to produce a collective concentrate (schlich, heavy concentrate). The tails of placer minerals don't accumulate. The tails return to the ocean in a secure form (in the same form as the original raw material).
