Recovery of lithium from spodumene-bearing pegmatites
Munson and Clarke [34] reported the first-ever deployment of a DMS plant for treating spodumene-bearing pegmatites at Edison mine, the USA, in 1949. A mixture of ferrosilicon and magnetite was used to prepare a media density of 2.70 for generating spodumene concentrate having a grade of 5.36% Li 2 O with a recovery of 47.4%

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.
