In coming years, global lithium production is expected to increase as the result of widespread electric vehicle adoption. To meet the expected increase in demand, lithium must be sourced from both brine and hard-rock deposits. Heavy liquid separation (HLS) and dense media separation (DMS) tests were conducted on the pegmatites …

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

Antimony has been known and used since ancient times, but its applications have increased significantly during the last two centuries. Aside from its few medical applications, it also has industrial applications, acting as a flame retardant and a catalyst. Geologically, native antimony is rare, and it is mostly found in sulfide ores.

sorting is carried out to give antimony lumps and tails that are −150+35mm. The −35+10mm fraction is heavy medium sepa-rated to discard a portion of gangue. Then the hand-selected low grade concentrate and the heavy product from the heavy media separation are ground to −10mm. This is carried out in three sep-arate sections.
