Gravity concentration. Gravity concentration is the separation of minerals based upon differences in SG.

Beneficiation of the gold bearing ore by gravity and flotation
2012年1月25日 Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and

Pre-concentration of vanadium from stone coal by gravity
2013年6月10日 In the gravity separation stage, 28.9% of the feed ore were rejected as final tailings, while the V 2 O 5 loss was 9.7%. The pre-concentration of vanadium from stone coal can improve the V 2 O 5 grade and decrease the content of high acid consuming minerals. The benefits of the pre-concentration process in terms of cost savings and
