Soviet manganese ore mining and beneficiation technology

Soviet manganese ore mining has a long history, is now the world's largest producer of manganese ore, the nineteenth century began to develop Qiatu La Nikopol deposits and eighties, from the late twenties of the twentieth century, Soviet Union Manganese ore production has always ranked first in the world. The Soviet Union also dominated the world's manganese ore trade. Since the 1980s, the annual production of commercial manganese ore in the Soviet Union has reached about 10 million tons. According to reports, the output in 1982 was 919.89 million tons. In 1983, the output was 9.253 million tons. The total reserves of the A+B+C1+C2 grades of the Soviet manganese ore have been determined to be 2.5 billion tons (average manganese content 23% to 26.4%). The Soviet manganese ore reserves account for almost 40% of the world's total reserves, second only to South Africa, ranking second in the world.
The Soviet Union is the world's largest consumer of the metal manganese. The amount of manganese ore consumed per ton of steel produced is almost double that of the major western steel producing countries. This is because the iron ore itself substantially of the Soviet Union manganese, and high sulfur content coal coke - and mass production of high iron-manganese and permanganate. In the consumption of manganese ore in the Soviet Union, 85% is used in the ferrous metallurgical industry, mainly as a compound for the manufacture of ferromanganese alloys and for the production of pig iron, about 4% for the chemical industry and the power industry, and about 11% for non-ferrous metallurgy. The pharmaceutical industry, agriculture and other areas of the national economy are used in the steelmaking process for deoxidation, desulfurization and refining ferromanganese. Manganese steel in a non-metal consumption are estimated to be at least 200,000 tons every year, for welding, a manganese salt, dry, oil industry, refining and casting of zinc and the like. In recent years, the quality of battery-grade manganese produced in the Soviet Union has declined, and dry battery manufacturers have used imported battery-grade synthetic manganese dioxide as an ingredient. The production of ferromanganese in the Soviet Union is also the highest in the world. The Soviet Union is now planning to equip six sets of new submerged arc furnaces made in Japan to further expand the production capacity of ferromanganese. The new equipment will be installed at the Nikopol smelter in Ukraine and the Chatstar smelting plant in Georgia, both adjacent to the manganese mine. Each set of furnaces can produce 120,000 tons of ferromanganese per year. Democracy has funded these new equipment and will be compensated for some of its products. Imported high grade manganese ore will also be used as a feedstock for these two smelters. The export volume of manganese ore in the Soviet Union has increased from 1.32 million tons in 1979 to 1.35 million tons in 1980. About 20% of them are supplied to Western countries, and 80% are supplied to countries that have passed through each other. According to reports, Western countries have stopped supplying in recent years.
Although the Soviet Union still maintains a leading position in manganese ore production, the shortage of high-grade manganese ore has developed. therefore. 1983 not only limited exports to countries that have been exchanged, but has also imported a certain amount of high-grade manganese oxide ore (>50% Mn) from Gabon and Australia in recent years. It appears that this is to compensate for the lack of high-quality manganese ore resources in the Nikopol and Chatura mines. According to reports, a new mine is currently in production at the Bourne Kolk Heights near Chatura, with a final production capacity of 10 million tons per year. To maintain its leading position in the manganese ore producers, the Soviet Union must further increase its investment in mines.
