Flotation applied to iron ores with complex mineralogy

A low-grade iron ore from one of the largest Mexican deposits was investigated. Flotation was performed on samples with different particle size distribution to verify the influence of liberation and evaluate iron losses in case of a possible screening prior flotation. The results show that there is a considerable difference in the quality of the final product from flotation between the samples

Froth flotation of Aljustrel sulphide complex ore

2017-5-26  Froth flotation of Aljustrel sulphide complex ore 759 Froth flotation occurs in an aqueous medium which involves aggregation of air bubbles and mineral particles with subsequent levitation of aggregates to the surface and transfer to a froth phase. The degree of particle surface wettability determines attachment and aggregation.

Research on the Flotation Process of a Complex Lead-Zinc

A kind of complex Pb-Zn ore has been studied. The run-of-mine grade of Lead was 2.84%, with the oxidation rate of 90.95%. And the grade of Zinc was 3.22%, with the oxidation rate of 87.9%. The optimal grinding fineness was about to 94.6%. Use the best reagent combination which obtained by condition test, the final results was that the grade of Lead concentrate was 23.41% and the recovery rate
