    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of frothflotation has improved the recovery of v

  • Lime use and functionality in sulphide mineral flotation

    The first method is a bulk Cu-Pb flotation followed by the activation and flotation of the Zn sulphide (Liu et al., 2000). The other common process to treat these ores is sequential flotation stages, each of which is optimized for the selective recovery of one mineral over the others.

  • Collectorless flotation of chalcopyrite and sphalerite

    The flotation of chalcopyrite and sphalerite from copper and copper-zinc ores has been achieved without using thiol-type collectors. Typically, a sulfide ore sample is first treated with sodium sulfide either during grinding or during the preflotation conditioning period, and then the chalcopyrite is floated with frother alone.

  • Recycling of process water in sulphide flotation: Effect

    Calcium and sulphate ions are two very common components in the process water from flotation of sulphide minerals. The origins of calcium and sulphate species in process water are the ore and flotation reagents such as lime for maintaining pH and NaHSO 3 for controlling the surface properties (Broman, 1980).
