The present paper provides information about the influence of particle size and synergism of collectors on the flotation of a very low grade auriferous sulphide ore. Mineralogical characterisation studies had shown that quartz made up 65% of the samp

The correlation between the flotation response of coarse particles containing gold and the reagent concentration system was examined using a very low grade auriferous sulphide ore. It was pointed out that an increase of collector concentration is nee
