Challenges in processing nickel laterite ores by flotation ...

10/06/2016  One stage rougher reverse flotation resulted in 0.5% nickel grades (at 33% recovery) which is not commercially acceptable. Quast et al. (2015a) have reviewed the application of various techniques of pre-concentration of nickel laterite ores prior to hydrometallurgical or pyrometallurgical process. They concluded that the complex mineralogy of nickel laterite ores makes it difficult to achieve any significant nickel upgrading by physical techniques (including flotation).

NICKEL AND COBALT ORES: FLOTATION

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 problem

In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse~ with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate. The ease of individual mineral flotability
