On the natural floatability of molybdenite
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 … Web22 de abr. de 2024 · Flotation tests using pure minerals of chalcopyrite and molybdenite demonstrate that the floatability of chalcopyrite decreased with increasing concentration …
