    Enhanced methods for nickel recovery from lowgrade ores

    Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4 Ni to 10-20. Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals.

    May 30, 2016 Different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation. With the BCL Selebi-Phikwe ore body, pentlanditepyrrhotitechalcopyrite co-occur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited. In the presence of pentlandite, pyrrhotite can even be galvanically depressed.
