Description
Technical field:
The present invention relates to a kind of treatment process of composite minerals, particularly a kind of from vanadium titano-magnetite the method for separation and Extraction metallic element.
Background technology:
Vanadium titano-magnetite is a kind of complex iron ore, contains beneficial elements such as iron, titanium, vanadium, chromium.For the comprehensive utilization of vanadium titano-magnetite, traditional method mainly is high temperature oxidation sodium roasting and two kinds of methods of high temperature reduction (Wang Wenzhong chief editor, " complex ore comprehensive utilization ").Wherein oxidation sodium leaching process is earlier with pelletizing sodiumizing-oxidizing roasting water logging vanadium extraction, soak behind the vanadium applied to pelletizing rotary kiln and reduce directly that----electric furnace is molten to be divided, can realize the comprehensive recovery of iron, vanadium, titanium, iron, vanadium, titanium recovery rate are respectively 85～89%, 58% and 74%, but Production Flow Chart is long, and the sodium agent consumes high, and pellet strength is poor after the vanadium extraction, easy efflorescence and ring formation when reducing in the rotary kiln, the vanadium titanium recovery rate is low; And that traditional high temperature reduction method is that iron ore pellets earlier gives heat (900-1000 ℃) through high temperature is fixed, reduce molten separation of iron and the vanadium titanium of dividing of----electric furnace through rotary kiln again, reclaim the vanadium titanium in molten iron blowing vanadium extraction or the slag, the rate of recovery of iron, vanadium, titanium is respectively 89%, 55% and 80%, realized that the ferrovanadium titanium comprehensively reclaims, reduce the sodium agent and consume, but still exist Production Flow Chart long (the pyrogenic processes processing of two steps), energy consumption height, the molten timesharing iron of electric furnace to be difficult to vanadium titanium separating effect instability, the vanadium titanium flow direction to control, shortcoming that the vanadium titanium recovery rate is low.
To be No. 02129512 Chinese patent application described " method and apparatus of separation of iron and titanium to prepare high titanium slag " " the coal-based direct reduction method " that propose contain briquet by layer 2-3 cloth reductase 12 0 minute in rotary hearth furnace with what system was shaken in rolling to application number, product after the reduction adopted through cooling normal temperature is broken to be separated with magnetic separation, have that pellet strength is poor, an energy consumption height and cost shortcoming of costliness too.Application number is " the cooled agglomerated pellet direct-reduction process " that No. 99115348.0 Chinese patent application described " comprehensive utilization vanadium titano-magnetite novel process " proposes, shortened technical process, having reduced the sodium agent consumes, improved the rate of recovery of three kinds of elements of ferrovanadium titanium, pellet strength is poor, the recovery time is long but still exist, the problem that production efficiency is low.
Summary of the invention:
The present invention is intended to overcome above-mentioned defective, provide a kind of from vanadium titano-magnetite the method for separation and Extraction metallic element, can direct production obtain reduced iron powder, high purity vanadium and rich titanium slag by this method, and technical process is short, energy consumption is low, ferrovanadium titanium recovery rate height.
Technical scheme of the present invention is as follows:
Of the present invention from vanadium titano-magnetite the method for separation and Extraction metallic element comprise following processing step: will the vanadium titano-magnetite breeze, reductive agent, additive, binding agent mix back compacting balling-up piece; The block vanadium titano-magnetite of the above-mentioned ball that is pressed into is packed in the rotary hearth furnace, be heated under 1200-1400 ℃ the temperature reductase 12 0-60 minute, obtain metallization and go back original product; The metallized product hot charging that makes is gone into furnace melting separate, obtain molten iron and vanadium titanium slag as steelmaking feed.
After described fusing separation circuit, from the molten vanadium titanium slag that divides, extract the oxide compound that obtains vanadium again, remaining titanium slag is as the raw material of titanium white production behind the extraction vanadium.
Described reductive agent is selected hard coal or various coal dusts such as brown coal or bituminous coal for use, and the amount of allocating into of reductive agent determines that according to the raw material iron level promptly reduced iron needs 105%～120% of theoretical consumption carbon amount.
Described vanadium titano-magnetite breeze and coal powder size account for 60～90% in-200 purposes.
Described binding agent is selected organic binder bond for use, and as polyvinyl alcohol and carboxymethyl cellulose etc., concentration is 0.3～1%.
Described additive is selected sodium salt or sylvite for use, and addition is 3～6% of a breeze amount.
Described electric furnace is selected electric arc furnace or induction furnace for use.
Described ball piece is meant and is pressed into the ball piece that diameter is 10～15mm.
Described vanadium titano-magnetite comprises vanadium titano-magnetite iron ore concentrate, ilmenite concentrate or other complex iron ores.
The present invention compares with prior aries such as high temperature oxidation sodium roasting reduction method, high temperature reduction method and cooled agglomerated pellet direct-reduction processes, and its advantage is:
1, because reduction temperature of the present invention directly reduces direct reduction temperature height such as (1100～1150 ℃) than shaft furnace (800～1200 ℃), rotary kiln (below 1050 ℃), cooled agglomerated pellet, reduction reaction speed is fast, recovery time is short, total reduction cycle than blast furnace (6～7h), rotary kiln (4～5h), tunnel furnace (4～6h), shaft furnace (3～4h), cooled agglomerated pellet reduces directly that (3～4h) production cycle shortens greatly;
2, degree of metalization of the present invention is up to more than 90%, and the vanadium titanium recovery rate is up to more than 90%; The production efficiency height, environmental pollution is little, social benefit and remarkable in economical benefits.
