Flotation Process For Low Grade Nickel Ore

NICKEL AND COBALT ORES: FLOTATION

Ore source Nickel distribution (%) Sulfur distribution (%) ... contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This problem can be overcome by using depressants like car-boxymethylcellulose (CMC) and guargum deriva-tives, although their cost accounts ...
