• The beneficiation of lithium minerals from hard rock ores

     · Dense media separation (DMS) or heavy media separation is a pre-concentration technique used to reject gangue minerals prior to grinding. DMS exploits the difference in specific gravity between the target and gangue minerals and is commonly used in the separation of spodumene from other gangue silicates.

    Mixed grinding with Na2S followed by water leaching was performed to extract Li from lepidolite. The leachability of Li increases dramatically in the ground mixture regardless of the mixing ratio over the range of 1 1 to 3 1 while only 4.53 of Li was extracted in lepidolite ground without Na2S. The leachability increased with an increase of the grinding time and ultimately 93 of the Li
