Gravity Separation & Concentration Methods

A combination of classification (initially screens to remove the coarser 'impurities', then hydrocyclones to remove the finer 'impurities' with some barite loss), gravity (calcite/fluorspar/silica from barite and sulphides from barite) and flotation (oleic acid/alkyl sulphonates/sulphates with sodium silicate as the dispersant and neutral to alkaline pH barite is depressed at acidic pHs).
