gravity separation. if the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore then it is possible to physically concentrate the valuable mineral and reject the rest. the easiest method for achieving this is by gravity separation.

gravity separationwikipedia

gravity separation.gravity separation is an attractive unit operation as it generally has low capital and operating costs uses few if any chemicals that might cause environmental concerns and the recent development of new equipment enhances the range of separations possible.

gravity separationhazen research

gravity separation relies on the difference in density of the mineral and the gangue. this technology can be applied to primary recovery preconcentration and final upgrading as well as recycling and soil washing.hazen's gravity concentration facilities are among the finest in the world.

how gravity separation works to recover metals and minerals

gravity separation has been used for centuries to separate different minerals and metals based on their specific gravity. some of the earliest recordings of this science in practice are from ancient egypt as workers panned for gold in the nile river.

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.
