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%).

Effect of Oxygen and Micro-Cracking on the Flotation of

2017-2-4  Abstract—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. The desired effect of micro cracking the ore is that the nickel sulphide minerals will become activated and this activation will render these minerals more susceptible to react with potassium amyl xanthate collectors, resulting in a higher recovery of nickel and hinder the recovery of other undesired minerals contained in the ore. Higher nickel recoveries were obtained when pure oxygen was used as a bubbling

The ore contained magnetite tolerably. Flotation process was tried on the ore crushed under 100mesh with pine oil, xanthate and various other reagents, but we could not concentrate the ore without previous desliming. The slime under 25 μ was removed by sedimentation process. By desliming the ore, the weight was reduced to the half of the feed.
