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 … WebSperrylite and pyrite had poor natural floatabilities under both alkaline and acidic conditions, indicating that their floatability is strongly dependent on their interaction with collectors. The poor recovery of this relatively hydrophilic mineral is due to poor collector adsorption of the collectors at pH 9 which is the usual pH in operating plants.
