  • Platinum - Palladium Flotation

    In larger scale tests using the best conditions previously determined for the MBT-sulfuric acid flotation scheme, ore charges to the rougher flotation circuit were increased to 5,000 grams. The average results of 10 tests are given in table 6. Platinum-palladium recovery values were similar, but concentrate grades were higher than those obtained using 1,600-gram charges (table 4). The tenor of ...

  • Recovery of PGMs from an oxide ore by flotation and leaching

    Froth flotation is the process used in the Platinum Group Metal industry to upgrade the run-of-mine ore for subsequent processes such as smelting and hydrometallurgical PGM refining. The PGM concentrator plants achieve high PGM recoveries (>85%) when treating prestine (unweathered) sulphide ores. However, the depletion of prestine sulphide PGM bearing minerals has triggered interest in ...

  • Flotation Reagents - Mineral Processing Metallurgy

    Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
