, the recovery rate climbs along with the increase of collector dosage, yet, when the concentration of RFP-138 amounts 300 g/t, almost 100% of collophane is floated, while, for hematite flotation, RFP-138...Trans. Nonferrous Met. Soc. China 23(2013) 501-507 Separation behavior and mechanism of hematite and collophane in the presence of collector RFP-138 Kan-ping YU 1,2, Yong-fu YU 1,2,3, Xiang-yang XU1......
and Technology Beijing, Beijing 100083, China)Abstract:The possibility and effect of Rhodococcus erythropolis (R. erythropolis) as a flotation collector for hematite were investigated. The surface... and cell concentration of 75 mg/L. Iron concentrate with the grade of 50.08% and recovery rate of 76.41% is recovered from the mixture after one-stag flotation. The chemical adsorption of the strain onto......

in liberation size. The experimental results state that selectivity would be improved by increasing collector concentration and reducing the flotation time. Key words: celestite; flotation time; collector... and flotation rate of coal is increased by increasing collector concentration at higher frother dosage. However, they also proposed that the net recovery of solid decreased with increasing the collector......
