potassium ethyl xanthate gold flotation

  • Effect of Potassium Ethylxanthate Degradation

    The flotation response of molybdenite in the presence of KTTC, KEX, and fuel oil No. 2 was examined using the Hallimond tube flotation procedure. Table 1 shows that molybdenum flotation decreased from 51 to 38 pct when the ratio of KTTC to KEX increased from 1:1 to 5:1. Note that the KEX concentration was constant at 10 -5 mol/L while the KTTC varied from 10 -5 to 5 x 10 -5 mol/L. The

  • Froth flotation Wikipedia

    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

  • Gold Flotation Mineral Processing & Metallurgy

    Ethyl xanthate is not so commonly used as the higher xanthates for this type of flotation. The liquid flotation reagents such as Aerofloat 15, 25, and 31 are commonly used in conjunction with the xanthates. These reagents possess both promoter and frother properties. When malachite and azurite are present, reagent 425 is often a useful promoter. This reagent was developed especially for the

  • Xanthate an overview ScienceDirect Topics

    For ethyl xanthate, the presence of silver in gold leads to silver xanthate formation at a potential proportionately lower than for dixanthogen formation on pure gold (Leppinen et al., 1991). As a consequence, the flotation of gold–silver alloys can be achieved at potentials considerably lower than that for gold. Xanthate ions chemisorb on silver at potentials below the region at which

  • Sodium ethyl xanthate Wikipedia

    Sodium ethyl xanthate (SEX) is an organosulfur compound with the chemical formula CH 3 CH 2 OCS 2 Na. It is a pale yellow powder, which is usually obtained as the dihydrate. Sodium ethyl xanthate is used in the mining industry as a flotation agent. A closely related potassium ethyl xanthate (KEX) is obtained as the anhydrous salt.
