flotation of cassiterite with modified fatty acids

  • Selective Flotation of Cassiterite from Calcite with

    The development of selective collectors for cassiterite flotation is a relatively popular field []Oleic acid and its derivatives are the most widely used collectors in oxidized ore flotation [9,10,11,12]The downside of this fatty acid collector is its low selectivity and poor solubility at low temperatures []Ptolyl arsonic acid was proved to be a selective collector for cassiterite, yet
