  • Which type of ores are concentrated by froth flotation

    The froth flotation method is used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition. This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil.

    Various flotation reagents are added to a mixture of ore and water (called pulp) in a conditioning tank. The flow rate and tank size are designed to give the minerals enough time to be activated. The conditioner pulp [1] is fed to a bank of rougher cells which remove most of the desired minerals as a concentrate. The rougher pulp [2] passes to a bank of scavenger cells where additional reagents may
