Jul 12, 2021 · For the disseminated copper-sulfur ore, the preferential flotation process is adopted, and the sulphur in the tailings must be re-floated. To reduce the consumption of sulfuric acid during the floatation and ensure safe operation, the process condition of low alkalinity should be adopted as far as possible. Bulk-separating flotation

Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include i. Dephosphorization. ii. Desulfurization. iii. Desiliconization. iv

For sulfide ores, a different process is taken for beneficiation. The ore needs to have the sulfur removed before smelting can begin. Roasting is the primary method of separating, where wood was placed on heaps of ore and set on fire to help with oxidation. [4] [5] 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2

Nov 05, 2020 · 22.4: Beneficiation. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of
