    The material composition of kaolin raw materials with the content of Al2O3 – 17,21; SiO2 – 66,27; Fe2O3 – 0,51; TiO2 0,574 was studied. The main valuable minerals are kaolinite, halloysite, muscovite, quartz, rare marks of tourmaline, ilmenite. Particle size analysis of kaolin raw materials shows that the largest mass is represented by the size class (- 0,05+0 mm) – 43,08 %. 79,74 % of alumina with its content of 32,0 % is in the size class (- 0,05+0 mm), and it can be used as a raw material for further processing into alumina or as a universal filler for production of paper, rubber, cable, plastic and perfumery products

    The results of studies on the production of pellets for the metallurgical stage based on manganese concentrate with a manganese content of 34 %, obtained from waste manganese-containing sludge, are presented. Kaolin and highiron diatomite in combination with calcium oxide and coke were tested as binder components of charges. Manganese- containing pellets were produced by composition pelletizing in a Eirich high-speed mixer-granulator. The size of pellets in the form of rounded granules was in the range of 5 - 10 mm. Sintering roasting temperature of pellets was 1150 - 1200°C. Strength of roasted pellets was 1 313 with kaolin as binder, 1 940 with diatomite, and diatomite with lime addition – 2058 N/pellet respectively

    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

    On the possibility to obtain manganese concentrate from manganese-containing tailings

    Get PDF
    The paper presents the results of studies intended to separate minerals by density in a heavy liquid. Chemical analysis found that the manganese content amounts to 16,32 % in the studied sludge sample. Manganese sludge was separated by specific gravity in M-45 heavy liquid (the aqueous solution of a complex salt of barium iodides and cadmium with a density of 3 000 kg/m3). The tailings sample was fractioned by specific gravity in the material with a particle size of -2,5 + 1,0 mm; -1,0 + 0,5 mm and -0,5 + 0 mm. The manganese content in the heavy fraction of 3 000 kg/m3 was 32,5 %. The manganese content in the light fraction varied from 1,7 to 2,5 %. Light fractions were represented by aggregates of quartz and calcite with manganese minerals. According to X-ray phase analysis, heavy fractions were mainly represented by minerals braunite, bixbyite, barite and hematite

    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

    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 %
