    Flotation and leaching processes are the most used for metal extraction in the mining industry. Froth flotation involves an intense treatment of their tails, affecting how water can be recycled in upstream operations. This is of great relevance, considering that the concentration circuits consume the highest proportion of water resources.

    Explain The Froth Floatation Method With A Neat Labelled

    Bubbles are formed due to this blown air. A rotating agitator at the centre of the floatation tank agitates the mixture and draws air into it to form bubbles. As a result, foam is formed which carries metal sulphide particles. The foam rises to the surface of water and floats. Therefore, this method is called froth floatation process.

  • What is the role of depressant in froth floatation process

    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.
