The selective flotation of pentlandite from a nickel ore
1995.6.1 The selective flotation of pentlandite from a nickel ore. 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.

CO2 sequestration in ultramafic ores: impacts on the efficiency of ...
2023.9.27 We present a carbonation-assisted flotation method for nickel (Ni) separation from low-grade ultramafic ores. The high process economics of conventional flotation of low-grade ultramafic ores makes Ni unrecoverable on an industrial scale. Based on the fundamentals of CO2 sequestration in minerals, we carbonated a l

Precipitate flotation I. Removal of nickel from dilute aqueous ...
Nickel can be completely separated from a hundredfold excess of cobalt by complexing the latter with nitroso-R-salt before flotation. Iron does not float on its own but recoveries of 50% can be achieved by entrainment of ferric hydroxide in nickel nioximate.
