The challenges in processing nickel laterite ores using flotation process were comprehensively reviewed Literature shows that flotation has not been successful to recover nickel from laterite or.Nickel flotation for High Talc OresFlotation of low grade nickel sulfide ores into a concentrate suitable for smelting, and at acceptable nickel recovery, can be challenging Alteration of the gangue minerals can mean talc is present in considerable quantiti Talc floats naturally and can be very difficult to depress without significant nickel.The Effect of Oxidation on the Flotation Behaviour ofBecause of the highly complex surface chemistry and mineralogy involved the results of flotation tests may often be difficult to interpret In this paper, the flotation behaviour of nickel copper ores processed in the Sudbury area is discussed with emphasis on the effect of oxidation on individual minerals, primarily pyrrhotite.

GV Rao, in Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2014 Problems Associated with Flotation of Sulfide Nickel Minerals In sulphide nickel ores, the predominant nickel bearing mineral pentlandite is almost always is associated with pyrrhotite and often found to be associated with other sulphides like iron sulphides (pyrite).
