Dense media separation (DMS) is a gravity separation method in which a suspension material such as magnetite or ferrosilicon is used to form a medium denser than water in separation. This method is used to separate valuable materials from waste. Multotec supplies a complete range of DMS processing equipment, which includes a customisable and industry-proven range of …

A typical gravity concentration circuit recovers about 50–60% cassiterite (Lepetic, 1987) but significant values in the fine size are lost in the gravity tailings.Application of flotation and development of selective collectors have made it possible to recover fine cassiterite from the gravity tailings, which has resulted in improvement of overall plant recovery values to over 80%.

Heavy media beneficiation circuit and media recovery circuit. ... Typical results in a coal beneficiation plant using spirals to treat fine coal indicated very little deterioration in performance with the under-slimed and deslimed feed material (−500 mesh) even when the feed contained ~50% of −500 mesh material. However, the clean coal ash ...
