NICKEL AND COBALT ORES: FLOTATION

2016-6-7  A typical example of a nickel sulRde plant operat-ing with highly Soatable talcose gangue is at Trojan mineinZimbabwe.TheZimbabweansulRdedeposits contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This ...
