The Effect of Hydrodynamic Conditions on the Selective ...

In this research, selective flotation was carried out using two pitched blade turbine impellers with diameters of 6 cm and 7 cm to float copper and nickel. The main focus of this research was to generate optimum hydrodynamic conditions that can effectively separate nickel and copper from gangue minerals.

2019-1-1  In first stage of flotation, copper sulphides were floated followed by nickel sulphide from the copper tailings. In the Ni flotation stage, four rougher concentrates (RC 1, RC 2, RC 3, RC 4) were separately collected over the respective time intervals between 1, 3, 7, and 15 min. All rougher concentrates were weighed, filtered and dried for ...

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 ...

Influence of sulfur-containing ions on selective flotation ...

1. During the reorganization of a beneficiation plant with water recycling, a close correlation between the selectivity of flotation of complex copper-nickel sulfide ores and the sulfoxide ion concentration in the recycled water and pulp was found. This necessitated the control of the ionic composition of the pulp. 2. Correction of the ionic composition of the pulp should be achieved by adding ...

Dissolved-Air Flotation of Metal Ions

2007-6-18  Metal ions (copper, nickel, zinc, and ferric ions) were separated from dilute aqueous solutions by dissolved-air flotation. The ions were either precipitated as sulfides or floated (as ions) by xanthates. Copper and nickel were selectively sep- arated; promising results were obtained with single, binary, and ternary mixtures.
