The Effect of Gangue Mineralogy on the Density

2016-2-15 · Density separation is widely used to pre-concentrate ore minerals and reject unwanted gangue prior to the main processing stage of an ore (e.g. flotation). For base metal sulfide ores, dense medium separation (DMS) is used to separate the sulfide minerals, which are relatively dense, from the less dense silicate gangue minerals.
