The beneficiation of lithium minerals from hard rock ores: A review
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.

Dense media separation
Dense medium separation (DMS) is one of several preconcentration methods used for early waste rejection from run-of-mine ores at relatively coarse particle sizes prior to additional milling and beneficiation. DMS has been used extensively in the coal, diamonds, mineral sands, base metals and iron ore industries to produce either a final product or as a preconcentration step.
