concentration of ores study material for iit jee magnetic separation this method of is the froth flotation method this is the process for concentration of primarily sulphide ores it has dash is concentrated by magnetic separation method.,the method used for the concentration of sulphide ores is,the principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by the water. hence the method used for the concentration of sulphide ores is froth flotation.
calcite ores typically contain metal sulphide, silicate, or other zeta potential of calcite as a function of collector concentration (redrawn from somasundaran 1996) performed on refining the flotation process for calcite ores and jena ms, sahu p, dash p, mohanty jk (2013) beneficiation of limestone.,sulphide ore is concentrated by the method1. froth flotation ,this method is mainly employed for the concentration of sulphide ores. the method is based on the different wetting characteristics of the gangue and the
