  • Lime use and functionality in sulphide mineral

    2019-11-1  Lime in flotation, as a pH modifier, can also regulate not only collector adsorption, but also the effect of other commonly-used depressants such as sodium sulphide or sodium cyanide (Yoon, 1981, Ghiani et al., 1984, Wang and Forssberg, 1996). Cyanide acts by dissolving copper from the surface of the activated sulphides, thus preventing ...

  • Overdose NaHS Depression - Froth Flotation

    2020-6-29  Depression of sulphide surfaces (natural or sulphidised) by either sulphide or hydrosulphide ions is due to displacement of the collector from the mineral surfaces (this was well known in the 1950's - refer to Sutherland and Wark's classic book "Principles of Floatation", page 137 onwards, Figure IX-14).

  • Gold Precipitation Methods - Mineral Processing

    2020-6-25  Sodium sulphide has from time to time been suggested as a precipitant for silver and it should be a highly efficient reagent where silver alone is to be considered. The difficulty is that it rarely happens that the amount of gold in a silver ore is small enough to be negligible and as gold is not precipitated by sodium sulphide the method would ...

  • Dual effects of sodium sulfide on the flotation

    This study explores the flotation behavior of chalcopyrite in the presence of different concentrations of sodium sulfide (Na2S9H2O) at pH 12 under controlled potential conditions. It was observed that the flotation of chalcopyrite is not depressed completely when the pulp potential is low, even at high concentrations of sodium sulfide, i.e., 10−1–10−2 mol/L.
