Study of flotation gravitation of oxidized iron-containing enrichment tailings with enrichment of foam product in a narrowing trough

The analysis of works in the field of flotation, gravity and methods of their combination is carried out. The processes and apparatuses for the implementation of the combination of flotation and gravity processes are considered. A review is given on the use of tapering chutes in the Russian enrichment practice with a reflection of the positive effect. The analysis of the influence of flotation processes on the hydraulic classification has been carried out. A theoretical analysis of the flotation gravity of foam products in tapering chutes has been carried out. The mechanism of secondary concentration formation is described, as well as a possible method of intensification. Experimental studies of flotation gravity of oxidized ironcontaining tailings have been carried out. A detailed description is given of the methodology for studying the flotation and flotation gravity of oxidized iron-containing tailings. A scheme is presented for carrying out experiments for the enrichment of oxidized iron-containing tailings iron-bearing tailings by the flotation-gravity method with enrichment of the foam product in a tapering chute. The diagram shows the points of supply of reagents. The results of iron distribution by enrichment products are presented. Based on the results of the distribution of iron in the enrichment products of flotation and flotation gravity, a comparison was made, which shows the positive effect of the narrowing of the flow in the chute on the process of separating valuable mineral and waste rock. It is shown that the use of flotation gravity makes it possible to reduce the loss of a valuable component with tailings.
