Gravity Separation Gravity Separator Gravity

Gravity separation is the most effective method for processing ore and coal such as gold, tungsten, and tin. It is also commonly used to recover rare rocks, ilmenite, rutile, zircon, monazite, coltan, and coltan, and non-ferrous metal minerals, also used for sorting coarse-grained inlays and a few fine-grained hematite ores and manganese ore

Gravity Concentration Gekko

Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.

FL gravity density separators for minerals

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.
