metallurgy concentration of ore

Enrichment of Ore or Concentration of Ore

This method is used for concentration of sulphide ores of copper, lead and zinc. In this method, powdered ore is put in a tank full of water. And then, some Pine oil is added to it. In the tank the particles of sulphide ore are wetted by pine oil whereas the gangue particles are wetted by water. Then air is passed through this mixture.
