The invention is dealt with methods of production of manganese sulfates of different oxidation level. Two, three and quadrivalent manganese sulfates or their mixtures are produced by interaction of manganese oxides - MnO,Mn2O3,Mn3O4 and MnO2- of any origin with a concentrated sulfuric acid. The interaction is conducted in a vertical type beaded mill with glass beads of 1,5-2 mm diameter, in which in succession introduce a dissolvent non-reacting with a concentrated sulfuric acid, a manganous reagent and a sulfuric acid. They use the manganous reagent ground up to particle sizes of 1 mm and less and the 79.8-90 % sulfuric acid in a molar stoichiometrical surplus in respect to the manganous reagent of 1.20-1.72. Then engage the bead mill and conduct process at 5-25°C during 5-10 minutes at a ratio of masses of the dissolvent and the reagents of 2.33:1-10:1. The dissolvent is separated from the beads and the product by filtration. Manganese sulfate localized in the form of a film basically on the surface of beads and partially on the walls of the reactor manganese sulfate or a mix of manganese sulfates is dissolved in the sulfuric acid of a corresponding concentration or enter in the new process conducted in the same bead mill with a manganese sulfate (III) or (IV) in the capacity of an oxidizing agent. The technical effect is a fast and quantitative interaction of manganese oxides with a concentrated sulfuric acid at the room temperatures in conditions of a fine powdering of a solid phase in the bead mill.

Effect: improvement of consumer properties of manganese ore by increasing its ability to pelletizing, strength and resistance to abrasion, as well as improving the ecological properties of manganese concentrate and reduce its cost. Concentrate manganese contains low-phosphorus compounds of manganese, calcium, magnesium, silicon, iron, phosphorus, chlorine, and moisture. Chlorine ion is in the form of a mixture of chlorine-containing compounds Mn(OH)2OHCl+CaCl2in the following ratio, wt.%: calcium (in terms of oxide) of 6.5-20; magnesium (in terms of oxide) of 4,5-9; silicon (in terms of oxide) of 0.5-1.5; iron traces to 0.5; phosphorus from 0.01 to 0.05, chlorine-ion 0.1 to 2.5; moisture traces 5; manganese (in terms of oxide) of the rest. The concentrate has the appearance of granules with a ratio of the diameter of the pellets to its length is 1:0.25 to 10. 1 C.p. f-crystals, 1 table. The invention apply is the tion of high-grade manganese alloys and compounds, or for direct alloying of steel, as well as to cover the electrodes. Known manganese concentrate to cover the electrodes, containing oxides of manganese, silicon, aluminum, and sulfur and phosphorus in the following ratio, wt.%:Silicon (in terms of oxide) - Not more than 15 Aluminum (in terms of oxide) - Not more than 3 Sulfur is Not more than 0.1 Phosphorus (ratio of the mass fraction of phosphorus to the mass fraction of manganese - Not more than 0,00465 Manganese (in terms of oxide) - Rest (GOST 4418-75 concentrate manganese to cover the electrodes) The disadvantages of this concentrate are not high consumer properties, caused by low ability to pelletizing concentrate and relatively low strength and abrasion resistance, and relatively high production costs caused by the use of to obtain expensive concentrate beneficiation of manganese ores. Known concentrate manganese low-phosphorus containing oxides of manganese, silicon, and iron, sulfur, phosphorus and moisture in the following ratio, wt.%: Silicon (in terms of oxide) - 0.5 to 1.5 Iron - Tracks - 0,5 With the 5-250-94 Concentrate manganese low-phosphorus). The disadvantages of this concentrate are: 1. Its not a high consumer properties, caused by low ability to pelletizing concentrate and relatively low strength and abrasion resistance. 2. Its low environmental and consumer properties caused by the presence of small particles less than 0.4 mm up to 25%, which leads to dusting toxic substances, which is manganese concentrate. 3. The relatively high cost of known manganese concentrate, caused by the use of to obtain expensive concentrate beneficiation of manganese ores. The closest technical solution chosen by the authors for the prototype is known manganese concentrate, obtained from crushed manganese carbonate ores by treating them with a solution of hydrochloric acid with the addition of calcium chloride and subsequent treatment with lime milk and the Department of manganese hydroxide. Manganese concentrate obtained in a known manner, meets the quality of low-phosphorus manganese concentrate and contains after calcination compounds of manganese, calcium, magnesium, silicon, iron, phosphorus, BR> 1. Its not a high consumer properties, caused by low ability to pelletizing concentrate and relatively low strength and abrasion resistance. 2. Its low environmental and consumer properties caused by the presence of high content of chlorine, which leads to a significant emission of chlorine in the gas phase at the stage of smelting of manganese alloys - fugitive emissions of toxic chlorine compounds, including CL2. In addition, this manganese concentrate contains up to 25% of the fine fraction less than 0.4 mm, which leads it to dust toxic substances, which is manganese concentrate. 3. The relatively high cost of known manganese concentrate, caused by the use of to obtain expensive manganese carbonate ore. The proposed solution is aimed at increasing consumer properties of manganese ore by increasing its ability to pelletizing, strength and resistance to abrasion, and to enhance the ecological properties of manganese concentrate and to reduce its cost. The technical result is achieved by Nia, as well as iron, phosphorus, chlorine, and moisture - contains chlorine ion in the form of a mixture of chlorine-containing compounds Mn(OH)2OHCl+CaCl2in the following ratio, wt.%: Calcium (in terms of oxide) - 6,5-20 Magnesium (in terms of oxide) - 4,5-9 Silicon (in terms of oxide) - 0.5 to 1.5 Iron - Tracks - 0,5 Phosphorus - 0,01-0,05 Chlorine-ion - 0,1-2,5 Moisture - Tracks - 5 Manganese (in terms of oxide) - Rest and he has the form of granules with a ratio of the diameter of the pellets to its length is 1:0.25 to 10. In the analysis of patent and scientific and technical sources not identified technical solutions with the whole set of essential features of the claimed concentrate, which allows to make a conclusion on the conformity of the proposed technical solution to the criterion of paternopoli invention of "novelty." A comparison of the proposed concentrate with other technical solutions in this field of technology shows that you know the improvement of consumer properties of products of manganese concentrate, for example coatings for welding electrodes, by introducing manganese concentrate in the formation of products of calcium chloride, which contributes to the dilution of the core is ASS="ptx2"> However, information about the presence of manganese concentrate containing chlorine ion in the form of a mixture of chlorine-containing compounds Mn(OH)2OHCl+CaCl2and having the form of granules of specified size and has claimed a sum of known and unknown essential features of the claimed invention is not detected. The claimed technical solution is not obvious from the prior art, since obtaining granulated manganese concentrate with the stated parameters is a complex technical problem, requiring a large number of expensive experiments. In addition, it serves to eliminate bias in the fact that the presence of manganese concentrate adjustable additives chlorine-ion cannot improve its environmental properties. The presence of manganese concentrate chlorine ion in an amount of 0.1-2.5 wt.% in the form of a mixture of chlorine-containing compounds Mn(OH)2OHCl+CaCl2helps increase its consumer properties by increasing its ability to pelletizing, strength and resistance to abrasion, which allows you to refuse the introduction of manganese concentrate of calcium chloride at the stage of forming the finished product. In addition, SNGL phase in the smelting of manganese alloys, what enhances its environmental properties. Production of manganese concentrate in the form of granules of these dimensions allows to exclude from its membership a fine fraction and, consequently, dusting concentrate when working with it, which increases its environmental and consumer properties. In addition, production of manganese ore in the form of granules with the stated parameters increases the uniformity of distribution of manganese and other elements in the volume of the concentrate, as well as its fluidity, which ultimately improves consumer properties of the inventive concentrate compared to the prototype. The use for the manufacture of the claimed manganese concentrate instead of expensive concentrate beneficiation of manganese ore screening carbonate ore midnight with the content of manganese up to 25 wt.% (waste) can significantly reduce the cost of the proposed concentrate. The inventive concentrate manganese low-phosphorus is a crystalline substance of a dark brown colour. Before calcination, the concentrate is a mixture of hydroxides of manganese and its complex compounds, after calcination, an amount sets the Noah length. Chlorine ion in the concentrate is in the form of a mixture of chlorine-containing compounds Mn(OH)2OHCl+CaCl2that are obtained by the following reactions:2MnCl2+ Ca(OH)2+ 4OH-= 2Mn(OH)2OHCl + CaCl2(1) The inventive concentrate is expected to produce industry on THE newly developed. To validate the proposed technical solution was carried out the following work. The prototype low-phosphorus manganese concentrate was prepared as follows. Take a portion of powdered manganese carbonate ore containing 23.5% of manganese in the amount of 1.5 kg Fineness of grind was 0,125 mm Sample of manganese carbonate ore was treated with hydrochloric acid with the addition of calcium chloride to a pH of 1.6 and kept the pulp for 5 hours at 70oC. After filtration, the solid phase was washed with water at 70oC. the Filtrate, containing in g/l: 63,3 MP and 0,004 P, were used to produce manganese concentrate and wash water containing 16.4 g/l of manganese, used for preparation of lime milk with a concentration of 150 g/l, required for deposition of manganese ore. During the precipitation of the filtrate was added to the milk of lime to a pH of 9.2 and stirred at 45oWith the VI was progulivali at a temperature of 550oC for 1 hour. Got manganese concentrate containing, wt.%: 61,5 MP; 6,1 Cao; 1,45 MgO; 0,7 SiO2; 0,004 P; 0,21 Fe; 5,1 Cl-. According to the claimed technical solution of manganese concentrate was obtained from crushed screenings middlings enrichment - carbonate manganese ore deposits midnight containing wt.%: 19.2 MPtotal; 0,18 R; 3,2 FetotalFineness of grind was 0,125 mm Took a portion of the crushed screenings in the amount of 1.5 kg of This sample was repulpable in 4.5 l of calcium chloride solution containing 180 g/l, then typed hydrochloric acid to a pH of 1.6 and kept the pulp for 5 hours at 70oC. the Filtrate, containing in g/l: 61,3 MPtotal; 0,004 P used to obtain manganese concentrate and wash water containing 16.7 g/l of manganese, used for preparation of lime milk with a concentration of 150 g/l, required for deposition of manganese ore. During the precipitation of the filtrate was added to the milk of lime to a pH of 9.2, introduced the calculated amount of hydrogen peroxide for oxidation of 40-75% manganese and stirred at 45oC for 1 hour. Then precipitation of manganese concentrate was filtered, was repulpable at T:W=1: 10, was filtered, with the in and received high manganese concentrate, manganese, equal to a 55.4 wt.%, and different content in the product of chlorine-ion: 0,05; 0,1; 1,25; 2,5; 2,7 wt.% and other elements. The chlorine-ion content in manganese concentrate regulate the amount of oxidant (hydrogen peroxide) on the operation of the deposition and calcination of the product. One of the options received low-phosphorus manganese concentrate pellets 10 mm, the Ratio of the diameter of the pellets and the length was varied in the following range: 1:0,2; 1:0,25; 1:5; 1:10; 1:12 by changing the length of the pellets. To do this, wet a hydroxide of manganese without drying filed in special granulator, connected to the furnace. This granulator hydroxide manganese screw through the holes of 10 mm was applied in the drying chamber. A special knife cut pellets of a given length, which by an inclined chute was admitted to the drying chamber. The granules were dried at a temperature of 105oWith, and then progulivali in a furnace at a temperature of 550-800oC for 0.5 to 2 hours. For each option held by 3 experience and received 100 g of the product was investigated to determine the chemical composition, particle size distribution, environmental and consumer properties and the cost of concentrate by standard methods. The results are shown in the table. The optimum chlorine-ion content in the concentrate is 0.1-2.5 wt.%, and the ratio of the diameter of the pellets to its length is 1:0.25 to 10 (experiments 3-5). The reduction of chlorine-ion content in the concentrate is less than 0.1 wt.% (experiment 2) does not allow to significantly improve the consumer properties of the concentrate. The increase of chlorine-ion content in concentrate more than 2.5 wt.% (6) does not lead to further significant improvement of consumer properties of the concentrate. This significantly increases the consumption of hydrochloric acid in the leaching operation, increases the cost of concentrate and worsen its environmental properties. When the magnification ratio of the diameter of the pellets of the concentrate to its length of more than 1: 0,2 (experiment 2) is the shearing edges of the granules and the increase in the number of small fractions, the reduction ratio of the diameter of the pellets of the concentrate to its length less than 1: 10 (6) is the breaking of granules in length and increases the amount of fine fraction, which leads to deterioration of environmental and consumer properties of the inventive concentrate. The claimed technical solution is tested in a production environment JSC "CHMP" with the release of pilot batches of high-quality manganese concentrate in the form of granules with a positive result. The obtained manganese concentrate meets the requirements of THE newly developed. 1.
