  • The Recovery of Copper from Smelting Slag by Flotation ...

    Feb 08, 2017  Abstract. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.

    OverviewSulfide smeltingHistoryConcentrationFroth flotationHydrometallurgical extractionConcentrate and copper marketingSee also

    Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters

    A series of batch laboratory flotation tests was conducted on a suite of different calcium-ferrite slags made in continuous pilot plant smelting trials. The slags included a moderately reduced low copper slag, a more oxidised high copper slag, a very reduced low copper self-pulverising slag, and a moderately reduced low copper Escondida slag.

  • 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.

  • Froth flotation - Wikipedia
