    With sufficient mineral liberation, having magnetic separation before gravity separation enhances the separation of magnetite (in addition to pyrrhotite) from scheelite; magnetite density (5.15 g/cm 3) is close to that of scheelite (6.01 g/cm 3) ; hence, their separation with gravity method may not be efficient. Therefore, gravity separation would be applied to the non-magnetic product of magnetic separation.Extraction of Tungsten JXSC Machine,2018-11-1 · Tungsten ore processing methods are mainly hand selection, aviation model selection, gravity separation, flotation, magnetic separation and electrostatic separation.
