Flotation Of Cu And Ni
Copper Nickel Flotation
Flotation responses were studied in both laboratory and pilot plant tests. Pilot plant flotation responses were similar for both samples resulting in grades of 12.2 pct Cu and 2.5 pct Ni for the pit sample and 12.2 pct Cu and 2.1 pct Ni for the shaft sample. Weight recoveries were 2.5 pct for the pit sample and 5.2 pct for the shaft sample.

The removal rates of Cu 2+ and Ni 2+ with DS − were much faster in the presence of Trien than for simple aquo ions, and the final metal concentration was significantly lower. Surface tension measurements showed that Trien enhanced the surface activity and adsorption density for SDS Cu(II) and SDS Ni(II) solutions.

Differential Flotation of Chalcopyrite, Pentlandite
18-7-2013· AbstractA new method for the treatment of Ni–Cu sulphides ores from the Sudbury region by differential flotation is presented. The method exploits the ease of chalcopyrite floatability in complete or virtual absence of collector, but in the presence of sulphur dioxide, an effectivecomplexing agent such as diethylenetriamine (DETA) and a frother.

Cu(II) and Ni(II) activation in the flotation of
This study has shown that the silicates of quartz, lizardite and chlorite can be activated with Cu(II) or Ni(II) and floated with xanthate in the pH region 7 to 10, where copper and nickel form positively charged hydroxides that adsorb on the negatively charged silicate surface. This activation is much more pronounced for copper than for nickel.
