Description
Specification Metallurgical method of ferronickel by blast-furnace smelting nickel oxide ore without crystal water Technical field The present invention relates to a method of blast-furnace smelting, more particularly to a metallurgical method of ferronickel by blast-furnace smelting nickel oxide ore without crystal water. Background of the invention Global extensive uses of stainless steel and special steel lead to supply shortage and rapid rise in price of nickel metal, a main element used to smelt stainless steel and special steel. Conventional technology is mature that nickel metal is produced by mainly extracting from nickel sulfide ore, which covers 30% of the nickel resources on the earth. But at present, reserves are in shortage and resources are in crises after continuous exploitation for near one century. People have to pay more attention to the extraction of nickel metal from laterite nickel ore (nickel oxide ore) covering 70% of nickel resources on the earth. The main reason that laterite nickel ore haven't been exploited on a large scale for a long time is that the technology extracting Ni from such mineral resources is characterized by high cost, technological complexity, low yield, severe pollution. At Present, for high-grade laterite nickel ore (nickel content above 2.0%), ore-smelting furnace is generally used to smelt on the international, however, this method is provided with disadvantages such as high power consumption, severe environmental pollution and low yield of intermittent production. For low-grade laterite nickel ore, hydrometallurgy is commonly used, namely, a method of vitriol 2 comprising the steps as follows: Crushing and sieving raw ores, wherein the raw ore block in particulate diameter of 10-60mm is used as raw material for blast furnace smelting and mixing the feed of ore powder in grain diameter smaller than 10mm with coke powder, calcium lime/limestone and sintering to obtain sintered ore blocks; Crushing and sieving the sintered ore blocks, wherein the sintered ore block in particulate diameter of 10-50mm is used as raw material for blast furnace smelting and sintering the ore powder in particulate diameter smaller than 10mm again. Mixing sintered ore block, raw ore block, coke, limestone/calcium lime, dolomite and fluorite and blast-furnace smelting to obtain ferronickel, wherein the weight ratio of the following additives to sintered ore is: fluorite 0.3~8% dolomite 0~8% limestone/calcium lime 4-35%. The raw ore block may not be added as metallurgical raw material in smelting steps. Preferably the main component of the nickel oxide ore and the weight ratio of its own are: Nickel: 0.5~4.5%; Chrome: 0.3~12%; iron: 38~55%. The preferable weight ratio of the additives to the sintered ore is: fluorite 0.3~5% dolomite 0.5~5% limestone/calcium lime 8-15%. Preferably the content of CaO in limestone is greater than 50%, while 4 soaking, ie converting solid-state nickel oxide, chromic oxide, ferric oxide or the like in the laterite nickel ore to mixed solution of liquid-state nickel sulfate, chrome sulfate, ferrite sulfate (Fe 2 ) and the like, then separating nickel sulfate thereby, forming nickel metal only accounting for 1-2% of the gross by electrolysis with all the other components wasted. The process equipment is characterized by large one-off investment, complex process, long periodicity, severe environmental pollution. Blast-furnace smelting may also be use, however, because Cr 2
O
3 as concomitant commonly exists in laterite nickel ore, extremely high melting point of its own can lead to large viscosity of molten iron water so that iron water containing nickel and chrome can't flow out successfully and cause severe results such as frozen furnace and damaged furnace. Many corporations and research organizations at home and abroad have studied the technology for a long time that ferronickel (nickel iron) can be obtained by blast-furnace smelting laterite nickel ore in one-step way, but hitherto no success is reported. Consequently, it is urgent problem to be solved in this business to find an industrial method that nickel iron is smelted directly from laterite nickel ore, which is characterized by high efficiency, low consumption, high yield, low cost and no pollution or little pollution. Summary of the invention To solve the above problem, the present invention provides a metallurgical method of ferronickel by blast-furnace smelting nickel oxide ore containing no crystal water in one-step way. The above inventive object is achieved by the following technical proposal. The invention provides a metallurgical method of ferronickel by blast-furnace smelting nickel oxide ore containing no crystal water, mainly 3 that of CaO in calcium lime is greater than 80%; the content of Mg in the dolomite is higher than 10% and that of CaF 2 in dolomite is bigger than 80%. Compared with the prior art, furnace temperature can reach up to about 1700 " C in the conventional blast-furnace smelting technology, chrome contained in nickel oxide ore mainly exists in the form of Cr 2 0 3 whose melting point is about 23000 C, consequently, the reduction degree of chrome in nickel oxide ore is limited to cause bad fluidity of the obtained iron water and easily to produce phenomenon of frozen furnace, and even result in accidents. In metallurgical method of ferronickel by smelting nickel and chrome iron ore provided by the present invention, the addition of fluorite can lower the influence of chrome on furnace temperature effectively and raise the fluidity of iron water, meanwhile, because the addition quantity of fluorite in metallurgical method provided by the present invention is strictly calculated, the accidents, such as burnout of the crucible, caused by too high addition quantity of fluorite, can be effectively avoided. In the metallurgical method provided by the present invention, meanwhile, magnesium contained in dolomite may also be helpful to solve the problem on bad fluidity of iron water caused by chrome in nickel and chrome ores. Limestone can not only provide alkalinity, but also can balance the above two additives. The metallurgical method of one-step blast-furnace smelting provided by the present invention is characterized by short technical process, high yield of continuous production, total extraction of nickel, chrome and iron in laterite nickel ore once for all, high ratio of resource utilization. The slag obtained by smelting is an excellent raw material to produce concrete, except the exhaustion of a given mass of CO 2 gas, no other solid or liquid wastes are produced and there is no pollution. By contrast, the metallurgical technology of blast-furnace smelting 5 provided by the present invention has some advantages, for example low cost. Blast furnace in the technology provided by the present invention can consume 150-200 kilowatt-hours per ton iron, while the conventional ore smelting technology need consume 2000-4000 kilowatt-hours and coke of 0.5 ton per ton iron; For example economic resources, high yield, namely the mean yield of blast furnace is bigger than that of ore-smelting furnace; such as little pollution, little dust, high recovery rate of the raw materials which are respectively 97-98% for iron, 99% for nickel and 40~-50% for chrome.
