What is Concentration of Ore Definition Physical
Froth floatation. In this process, finely ground ore or we can say pulp of ore is passed into the bioreactor along with little oil. The oil which is generally used in the froth floatation process is pine oil. The bioreactor contains water onto which the mixture of ore plus oil is added through an inlet.
