NICKEL AND COBALT ORES: FLOTATION
The reagents generally known to modify the slime surface charge and reduce their adverse inSuence on pentlandite Sotation are dextrin, sodium pyrophosphate, sodium silicate, sodium carbonate, guargum and CMC Among these reagents CMC has been foundto be the best, despite the high concentra tion required (more than 2 kg t1)The reagent practice in the flotation of nickel and copper–nickel ores depends on three basic factors: mineralogy of the ore, flowsheet employed in the treatment of a specific ore, and degree of liberation The presence of hydrophobic gangue represents a major problem in the treatment of both nickel and copper–nickel ores For the depression of hydrophobic gangue organics, the depressants Handbook of Flotation Reagents ScienceDirectHowever, the poor nickel floatability into the bulk concentrate indicated that TBP can be an effective flotation reagent for differential flotation of CuNi bearing concentrates to preferentially depress pentlandite TBP is likely to play duel role in augmenting the copper recovery while depressing the nickel sulphide mineralsNickel Ore an overview ScienceDirect Topics

Froth flotation Wikipedia
Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario Various flotation reagents are added to a mixture of ore and water (called pulp) in a conditioning tank The flow rate and tank size are designed to give the minerals enough time to be activated The conditioner pulp [1] is fed to a bank of rougher cells which remove most of the desired minerals From sulfide ores Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubblesNickel processing Extraction and refining BritannicaThe mine tailing is represented as flotation tailings in the form of mud containing residual metal sulfides in the form of chalcopyrite, pyrite, pyrrhotite and pentlandite and reagents after flotationDevelopment of a Combined Flotation and High Pressure
