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 ...

Bulk flotation An efficient procedure for nickel recovery is to combine copper sulphate to activate pentlandite with guar gum to depress talc. This is the method which has been used for the flotation of nickel ores in industry and which we have termed the "standard bulk float". A selection of results for this ore is given in Table 3.

In nickel-copper sulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation [].Large amounts of serpentine in the flotation concentrate reduces the …

Flotation kinetics of pentlandite and violarite contained in copper–nickel ores and the effect of crystallochemical peculiarities of the minerals on their flotation features are studied.
