Application of Enhanced Gravity Separators for Fine ...
While treating tungsten in multi-gravity separator, it has been reported that MGS has significantly high separation sensitivity to rotational speed. Though the test showed an increase in WO 3 content with an increase in wash water, tilt angle, shake frequency, and amplitude, the percentage of yield also decreased [ 39 ].

Dense Medium Separation - An Effective and Robust Pre ...
Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.
