Different minerals with large density difference can be separated by gravity separation process. The density of barite is 4.5g/cm3, which is much higher than other common gangue minerals (such as ...
Further research suggested that the combination of sodium silicate with alum or carboxymethyl cellulose (CMC) could reduce the dosage of depressant, as alum was effective in suppressing barite and CMC is a common inhibitor of calcite. 4, 83 In a flotation experiment of monazite from hematite and quartz mixtures with hydroxamic acid, a …
Gravity Separation. The usual methods for barite gravity beneficiation are crushing, screening, and jigging beneficiation processes to obtain higher-grade concentrates, and …
Flotation of the second step has two ways: 1 Inhibiting barite and floating fluorite: inhibitors have lignin sulfonate, sodium silicate, NAF, dextrin, aluminum salt, ferric salts; captor has oleic acid. 2 Inhibiting fluorite and floating barite: adjusting the PH value the slurry to strong alkalinity by the sodium hydrate, using the citric acid ...
