  • Selective inhibition of sodium tripolyphosphate on calcite

    Froth flotation is a common way for selective separation of magnesite and gangue minerals,. Reducing the content of impurity quartz in magnesite has been reported systematically [13],[14] . It is a common method to remove quartz by reversing flotation with cationic collector for improving the separation efficiency of magnesite and quartz [13] .Reagent dosages control based on bubble size,2016-8-1 · Because the froth size distribution of the flotation process is intimately related to the reagent dosage, under the same working conditions, different reagent dosages correspond to the different distribution of bubble size. However, for the same reagent dosage, the distribution of bubble size could be similar.
