Froth flotation is a vital mineral concentration process, utilised to recover a vast array of diverse minerals holding valuable commodities. Such commodities include copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash. In the flotation process, ore is ground to a size sufficient to adequately liberate desired minerals from the waste rock (gangue); [.]
