    The paper presents the results of laboratory studies on the flotation of copper-molybdenum ore from the Kazakhstani deposit using a combined reagent. A combination of butyl xanthate, a noninogenic collecting agent with a thioamide group – TC-100 thionocarbamate and higher aerofloat (Reafloat series) was used as a combined flotation reagent. The ratio of the components of the combined reagent was, in %: 85:15:5. The combined flotation reagent was preliminarily passed through a T18 digital ULTRA-TURRAX disperser before flotation to obtain a reagent microemulsion. The use of a microemulsion of a combined reagent increases the extraction of copper into the coppermolybdenum concentrate by 3,69 %, the extraction of molybdenum by 6,05 %

    The objective of the study is to investigate the properties of water-air microdispersion of floatation agent solution. The air-water emulsion of flotation agent solution is obtained in the air-water microemulsion generator. Butyl airfloat, foaming agent C-7 and cationic collector butyltriethylenetetramine B-TETA have been studied as reagents. The factors influencing emulsion stability have been determined. It was found that the temperature increase worsens the stability of microdispersion, the optimal speed of the generator is 6 000 rpm and higher. Floatation agent solutions give stable microdispersions at different solution concentrations. The optimum microdispersion is obtained at a generator speed of 6 000 rpm from 0,5 g/l solution of butyl airfloat, from 50 g/l solution of C-7 and B-TETA. The particle size of the dispersion ranges from 41-59 μm

    The work presents the results of studies on obtaining ferromanganese concentrate from technogenic manganesecontaining raw materials with grain size less than 10 mm. It is found that the main valuable minerals of the feedstock are psilomelane, pyrolusite, bementite; among the rock-forming minerals, quartz and kaolinite, often saturated with finely dispersed iron compounds, prevail. Sieving and concentration of raw materials of - 10 + 5 mm and - 2 + 0,2 mm in two-chamber jigging machine with separation of two concentrates and tailingпs allowed to obtain a joint manganese concentrate with 35,1 % manganese content, 11,5 % iron content with 78,23 % manganese recovery. The obtained manganese concentrate is suitable for further metallurgical processing

    About the possibility of copper-bearing ore flotation processing of with the use of a combined flotation reagent

    Get PDF
    The paper includes the results of laboratory studies for the copper-bearing ore flotation with the use of a combined reagent. The combined flotation reagent was preliminarily passed through a UZDN-A1200T ultrasonic disperser before flotation to obtain a reagent microemulsion. The copper content in the concentrate was 21,5 % with extraction of 83,3 % in a closed cycle in the base mode. It was 21,8 % with an extraction of 88,3 % when a combined flotation reagent was used. There is an increase in copper extraction by 5 %. The combined reagent consumption is reduced by 15 % compared to the main technology

    Effect of the water-air emulsion size of the foaming agent solution on the non-ferrous metal minerals flotation ability

    Get PDF
    The research objective is to study the effect of the water-air emulsion size of the foaming agent solution on the flotation ability of non-ferrous metal minerals. An air-water emulsion of a foaming agent solution was obtained in a water-air microemulsion generator. It has been established that the supply of microbubbles to the monomineral flotation process makes it possible to increase the yield of minerals with different dispersion ability and accelerate the flotation process by 10 - 15 %

    Get PDF
    The paper contains the laboratory study results for the flotation processing of gold-containing tailings with the use of the composite reagent (CF). The CF flotation reagent is a microemulsion from a composition of sodium butyl xanthate and reaflot. A gold-containing concentrate was obtained with a gold content of 6,7 g/t with a recovery of 59,71 % in the basic mode. The use of the CF composite flotation reagent increases the gold extraction into the gold-containing concentrate by 3,77 %, as compared with the main collector - sodium butyl xanthate. The consumption of CF flotation reagent is reduced by 20 %

    The research presents the results of laboratory studies on the flotation processing of mature copper tailings using KF2 composite reagent. KF2 flotation agent is a mixture of sodium butyl xanthate, thionocarbamate, and composite aerofloat at a ratio of 1:1:3. In the base regime, a rough copper concentrate obtained had a copper content of 10,9 % with a recovery of 74,91 %. The use of KF2 composite flotation reagent increases the extraction of copper into rough copper concentrate by 5,31 %. This made it possible to obtain a rough copper concentrate with a copper content of 13,0 % and a recovery of 80,22 %. Consumption of KF2 flotation reagent is halved compared to the basic sodium butyl xanthate collector
