2016-1-6 Nickel ore dispersion before flotation using different reagents was investigated on a bench scale to improve metallurgical recovery and selectivity. The nickel ore had a content of 0.8 pct nickel and 14.5 pct MgO. A positive linear correlation between MgO and Ni was found. Carboxy methyl cellulose, both pure and combined with Na2CO3, was the best dispersant used. The most efficient collector ...

2013-12-1 Relationship between nickel grade and sulphur grade for the flotation tests for 65 kg S/tonne ore and 100 kg S /tonne ore. In order to determine the reason for the overall low amount of concentrate it is useful to examine the nature of both the nickel and iron recoveries as a function of sulphur recovery.

2019-1-1 The main aim of this study is to test a new type of an impeller in selective flotation of a low grade polymetallic Ni-Cu-PGE ore. The effect of impeller type and speed on bubble size and nickel grade and recovery was investigated. It was noticed that bubble size was independent of impeller type and speeds. However, the highest volume of small ...

This study investigated the effect of oxygen and micro-cracking on the flotation of low grade nickel sulphide ore. The ore treated contained serpentine minerals which have a history of being difficult to process efficiently. The use of oxygen as a bubbling gas has been noted to be effective because it increases the pulp potential.
