  • Flotation Depressants Mineral Processing & Metallurgy

    2020-06-04· First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color. This is because the froth

  • What is the role of depressant in froth floatation process?

    In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.

    Depramin® enhance the recovery of valuable minerals. Froth flotation is the most important method for separating valuable minerals from waste materials in ore deposits. This technique is a physico-chemical separation process based on a difference in hydrophobicity between the desired minerals and the unwanted minerals such as talc, serpentine, chlorite, anhydrite.

    In the rougher float depressants are added to produce a manageable froth and improve the grade by reducing the overall amount of the naturally floating gangue in the concentrates. Depending on dosage, depressants may also affect the recovery of the valuable minerals in the ore positively by slime cleaning or negatively by depression.
