2024.4.20 In this work, selective flotation of copper-nickel sulfide ore was achieved by using a selective depressant of sodium phytate. Microscale flotation results show that sodium phytate can selectively and effectively depress talc flotation, but has a minor effect on the floatability of chalcopyrite and pentlandite.

The selective flotation of pentlandite from a nickel ore
1995.6.1 Abstract. Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery and talc rejection but which does not reject pyrrhotite. Concentrates have therefore been of moderate grade containing as much pyrrhotite as

Nickel Sulfide - an overview ScienceDirect Topics
Nickel sulfide minerals such as pentlandite can, in general, be separated from their gangue by flotation using a thiol group of collectors like xanthates and alkyl dithiophosphates in the presence of variety of activators, depressants and dispersants. Since nickel sulfides contain other sulfides such as pyrrhotite, pentlandite and chalcopyrite, the enrichment of nickel is

Challenges in processing nickel laterite ores by flotation
2016.6.10 It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C.
