Nickel, Palladium and Platinum
The production methods for all three elements—nickel, palladium, and platinum—are complicated and dependent on the particular ore involved. In the case of nickel, the oxide ores are not generally amenable to concentration by normal physical separations, and therefore, the whole ore has to be treated. By contrast, the sulfide ores can be concentrated by flotation and magnetic separations
