Hydraulic WashingGravity The process by which lighter

Hydraulic Washing/Gravity Separation/Levigation The process by which lighter earthy impurities are removed from the heavier ore particles by washing WIth water is called levigation. The lighter impurities are washed away. Thus. this method is based on the difference in the densities (specific gravities) of ore and gangue.Get price

Recovery of Radiogenic Osmium

Copper concentrates are processed via smelting operations, resulting in the production of cathode copper, sulfuric acid and ammonium perrhenate. However, because the initial osmium-187 content in concentrates is less than 0.000005 wt.% (0.05 g t −1 ) the recovery of osmium from concentrates is not possible.Get price
