Effect of pre-agglomeration on the flotation of fine-sized gold …
In this study, the effect of pre-agglomeration on the flotation of fine-sized gold ore containing 11.3 g/t Au was investigated using olive and soybean oils. Firstly, the ore was floated using only collectors. Secondly, the ore was floated in the presence of vegetable oils and collectors. Finally, the effect of pre-agglomeration with graphite particles was tested again in …
