NICKEL AND COBALT ORES: FLOTATION

Flotation Practice in Nickel Sul\de Deposits Nickel sulRde minerals such as pentlandite can, in general, be separated from their gangue by Sotation using a thiol group of collectors like xanthates and alkyl dithiophosphates in the presence of variety of activators, depressants and dispersants.

Cobalt and Nickel Recovery From Missouri Lead Belt ...

Grinding The cobalt and nickel found in the Missouri Lead Belt ore have been charac­ terized by a complex inter­ locking of siegenite with chalcopyrite, sphalerite, and dolomite. An example of the interlocking is illus­ trated in figure 2. Grinding to achieve greater liberation was neces­ sary.

The flotation of slime–fine fractions of Mt. Keith ...

Apr 01, 2011 · The flotation of nickel sulphides in saline water at Mt. Keith has historically been difficult due to a low nickel grade and large amounts of serpentine minerals. A unique process, the split flotation, has been implemented at Mt. Keith to optimise pentlandite flotation. The grinding discharge is pumped to a two-stage cyclone classification.
