WebHoje · In addition to all of the above, the floatability of Ni(II) from aqueous solution by flotation-preconcentration technique using 1-(3,5-dihydroxybenzylidene)thiosemicarbazone as a complexing agent and oleic acid as a surfactant has not yet been reported in the literature, despite the fact that a vast array of reagents are available for the flotation … Web1. INTRODUCTION. Slime coating is related to fine gangue minerals generated due to the fine grind or the clayey nature of the ore. These fine particles exert detrimental effects on the flotation process due to the: i) adhesion of gangue slime to coarse particle surface, ii) slimes are bound to the value mineral surfaces through chemical reactions; iii) deposition …
