Mining and metallurgical complex
Mining complex processing ilmenite-titanomagnetite ores The project development of placer deposits of ilmenite-titanomagnetite ores Satka district organization and the mining complex with a complete production cycle from extraction to finished marketable products a wide range of (ferro-titanium, ferro-vanadium, zhelezhovanadievyh pellets deep metallization). Project implementation period is 3 years. The amount of project investment 25 million. dollars. Projected annual net profit of 5 million. High profitability due to excluding the cost of drilling and blasting and crushing redistribution, which on average is mine to 40-60% of the costs in the cost of the finished product. The work performed. Studied and analyzed research on enrichment-titanomagnetite ores ilmenite placer deposits and GRE experts Chelyabinsk Institute Uralmekhanobr (mode of occurrence, size distribution, category promyvaemosti, the extent and location of enrichment methods of improvement), the analysis of research VNIIMT to obtain pellets and methods of their choice to the metallization technological unit (ring stove). Results of operations: 1. Institute for Research Uralgipromez Comparative analysis concentrates processing ilmenite-titanomagnetite ores from different deposits proplavkoy on Ti slag and high alloy cast iron (V. Ni. Co) are flow charts. 2. VNIIMT proposed the main technical solutions for the production of ferro-titanium and ferro-vanadium with the hydrometallurgical treatment of metallic zhelezovanadevogo concentrate to produce profiled iron, material balance and alyumotermiicheskih fusion reactions. 3. The calculation of the total capital costs of construction (or reconstruction) of ferroalloys, is the main technical solutions. 4. Technical and economic assessment of mining and enrichment of ilmenite-titanomagnetite ores. The calculation of the annual profit of the plant. 5.Collected and analyzed the work of institutions: Uralmekhanobr, Uralgipromez, VNIIMT, Institute of Metallurgy UC RF Uralgiproruda, USTU, UralNIIChM, UC Institute of Economics of the Russian Federation, held earlier in the years 1978-2005 and for Kopanskii Medvedevskoe ilmenite and ilmenite-titanomagnetite deposits. 6. Technical and economic calculations for the production of ferro-titanium ferrovanadium obtaining of long iron. 7. Justification of the choice location Ferroalloy Plant. The results of the studies show that the placer deposit favorably in economic methods of production, exclusive of the cost method of processing (drilling, explosion, fragmentation, road transportation of overburden and waste rock). Also note that prirodnolegirovannye zhelezovanadievye pellets with a high degree of metallization used for electric production. The reserves of placer deposits is designed for 85-100 years and includes: 1700tysyach tonnes (consolidated after ilmenite) and 1.5 million tonnes (consolidated on titanomagnetite). Technology for processing. Extraction and enrichment of the first stage of rough concentrate is integrated directly into the pit, which establishes a mobile screening and processing complex. Because ore in nature is already prepared for their size distribution, it does not require additional crushing. Waste rock is piped directly to the reclamation of the waste pit. The concentrate is transported to the plant where it is carried out the second stage of enrichment and separation into zhelezovanadievy ilmenite concentrates. Next ilmenite concentrate mixture and okomkovyvaetsya after firing in a ring furnace at t - 1500 °, enters the electric-furnace DSP-1, 5 (3) with a temperature - 1000 ° C and plating up to 85 - 95%. Given the temperature - 1000 ° proplavku costs for electricity is reduced by 40 - 50%. In the smelting furnace EAF is ferrotitanium.Zhelezovanadievanadievy concentrate also okomkovyvaetsya furnace charge and firing after recovery from 90% goes to the metallization hydrometallurgical redistribution, in order to leach pentaksida vanadium. Pentaksid vanadium shihtovki after drying and also enters the smelting of ferro-vanadium. Leached pellets come in a blast or electric-processing in-doped vanadium iron. Zhelezovanadievye pellets can also be proplavit in furnaces ADI shop to obtain commercial iron and titanium slag, which are marketable. Technical and economic parameters of the plant. The performance of the first stage of the plant, with the volume of production in the rock mass 1 million. m3/year: • ilmenite concentrate 22-25 thousand tons (Ti-50%) • zhelezovanadevogo concentrate 16-20 thousand tons (V2O5 -0,9%) • zircon concentrate 0,500 tons of concentrates during processing get: • pentaksida vanadium = 90 tons. (20 000 $ / ton.) 90 x 20 000 = t $ 1.8 million • 9700 ton iron alloy. ($ 500 tn.) 9700tn. H5OO = $ 4.85 million • ferrotitanium PTI 35 = 7 thousand tons (3900 $ / ton.) 7 thousand tons x 3900 = $ 27.3 million 15 thousand tons of ilmenite concentrate ($ 300 tn.) 15 thousand tons x 300 = $ 4.5 million Prospects kompleksa.Tehniko and economic calculations to create a mining and metallurgical enterprises with a complete production cycle from extraction to finished marketable products for a wide range of waste technology show that this company is a highly efficient, mobile technology, high-yield and promising enterprise with the latest technologies. Nearby is the fundamental Kopanskoe ilmenite and titaniferous magnetite-ilmenite deposit with reserves of 2.4 billion tons (requiring more costly schemes of mining and enrichment and construction of a large MCC). Given that the annual deficit in the Urals on the iron-ore raw materials is 9-10 million tons. perspective of the project is enormous. Ferro Titanium is used in the manufacture of steel alloying, degassing and deoxidation. Steels, ferrotitanium, have improved mechanical properties.In the production of heat-resistant steels and stainless steels ferrotitanium binds carbon in titanium carbide, which improves weldability and corrosion resistance. Ferrotitanium contains from 20 to 75% Ti. Iron, which is part of ferrotitanium, lowers the melting point, which facilitates digestion more refractory titanium. Ferro Titanium alloy is an intermediate, which is used to produce stainless steel. Steel with the addition of ferrotitanium acquires special properties for corrosion resistance. For doping ton of steel requires about 0.5-2% titanium. Ferrotitanium get furnace aluminothermic method of ilmenite concentrate and titanium waste (low-interest ferrotitanium) or melting in an electric furnace iron and titanium scrap (high-grade ferrotitanium).
