Polyacrylamides in reverse cationic iron ore flotation: benc …
1. Introduction The iron content in the final tailings of industrial reverse cationic circuits is consistently high. Typical Fe tailings /SiO 2concentrate ratios reach the value of five or even higher. Silva et al. (2017) reported the results of the revaluation of a mechanical cells circuit of reverse iron ore flotation. …
Evaluation an anionic polyacrylamide flocculant with microbl …
Aqueous routes are of paramount importance in mineral processing. To adjust the solid contents, both concentrates and tailings, must be dewatered. A widely adopted method is the thickening, promoting the free settling of the mineral particles aided by coagulants or flocculants. This study analyzed the performance of different polyacrylamides as flocculants in the sedimentation of chromite …
