Froth flotation process class 12

Apr 19, 2021

May 22, 2021 What is froth flotation process Class 10? The Froth Floatation method is a method used for the concentration of metal ores. It is used for the concentration of sulphide ores. The ore particles become wet by oil while the gangue particles become wet by water. Air is blown in through a pipe and a rotating paddle agitates this mixture

    Jul 29, 2014 Froth Floatation Process. Principle: The principle of froth floatation is that sulphide ores are preferentially wetted by pine oil, whereas the gangue particles are wetted by water.. Collectors are added to enhance the non-wettability of the mineral particles. Examples of collectors are pine oil, fatty acids and xanthates

    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
