FLSmidth 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.

Halfbakery: Gold Separator

Dec 10, 2012  So a straight flow separation device like a classifier - where upwards flowing water is used to separate particles due to differential "terminal velocity" - tends to separate materials more due to size than density. Water is a viscous meduim and so higher terminal velocity is attribuited to - size, sphericity, then density. In that order.
