Description
Technical field
The present invention relates to vanadium field of chemical metallurgical technology, more particularly to a kind of side of v-bearing steel slag ion exchange method vanadium extraction
Method.
Background technology
V-bearing steel slag then be smelt vanadium titano-magnetite byproduct, be vanadium-bearing hot metal steel-making formed contain V2O5In 2-
10% slag (its calcium content is big compared with vanadium slag), its generation process has 2 kinds of approach, and a kind of is remaining vanadium in half steel through refining
Steel rear oxidation enters in slag, and another is that the molten iron direct steelmaking without the vanadium slag that blows obtains v-bearing steel slag.V-bearing steel slag has
Following features：(1) CaO and iron content are high, and crystallization is perfect, and quality is closely knit, and degree of dissociation is poor；(2) complicated component, and fluctuate larger；
(3) content of vanadium is relatively low, and vanadium Dispersed precipitate is in a variety of ore deposit phases, complicated occurrence state.Based on above feature, v-bearing steel slag vanadium extraction is still
It is so sciences problems.
Nearly million tons of the v-bearing steel slag that China discharges every year, not only pollutes environment, and cause the loss of valuable element vanadium.Mesh
Before, v-bearing steel slag vanadium extraction mainly has 2 kinds of approach, and one is that v-bearing steel slag returns to ironmaking Vanadium Concentrationin, produces height and contains vanadium slag, further
Vanadium extraction, i.e., add as flux using v-bearing steel slag and enter blast furnace process in sintering deposit, vanadium is fused in molten iron, and height is obtained through blowing vanadium
Grade vanadium slag, is used as vanadium extraction or the raw material of smelting ferrovanadium alloy.The technique can not only reclaim the valuable elements such as iron, manganese, and reduction
Iron steel than energy consumption, but easily cause phosphorus circulation collection in molten iron, aggravate slag dephosphorization task；And slag impurity is more, effective CaO
Content is relatively fewer, can reduce grade of sinter, increases ironmaking processes energy consumption, therefore the method fails to be promoted.It is another to contain
The processing method of vanadium steel slag is direct vanadium extracting method, there is the techniques such as sodium roasting, calcification baking, the roasting of drop calcium and direct acidleach.Sodium
It is the soluble sodium salt that Low Valent Vanadium is oxidized to 5 valency vanadium using salt or soda as additive by being calcined to change roasting, using water or
Carbonating is leached.The technique vanadium to turn leaching rate relatively low, sodium salt consumption is big, roasting process pollution air, is difficult to administer, and the technique
Be not suitable for V2O5The converter slag that content is low, CaO content is high.Calcification baking is to make roasting flux with lime etc., is soaked using carbonating
The Leaching Vanadium such as go out.This method has certain selectivity to material, there are problems that to general slag conversion ratio it is relatively low,
It is unsuitable for large-scale production.Drop calcium roasting is proposed by Amiri, high its purpose is to solve CaO content in v-bearing steel slag
The problem of causing vanadium hardly possible leaching.It is by slag and Na to drop calcium roasting3PO4, Na2CO3It is baking mixed, Na3PO4Combined to form with CaO
Ca3(PO4)2, vanadium and sodium generates water miscible sodium vanadate, and then water logging is leachable vanadium.But the method only rests on laboratory research
Stage, and phosphatic proportioning is big, cost is high, and there is presently no industrialization promotion.Direct acidleach refers to without calcining process, complete
Whote-wet method vanadium extraction but due in slag CaO content it is high, acid consumption is larger, and cost is higher；Acidleach process need to be entered in strong acid solution
OK, the leachate impurity obtained is more, it is difficult to carry out later separation.
CN102071321A proposes the method that vanadium, chromium are extracted from v-bearing steel slag with the potassium hydroxide medium of high alkalinity,
The method does not need high-temperature roasting, and reaction temperature is reduced to 160-240 DEG C, wet method vanadium extraction chromium, during effectively prevented C12、
HCl、SO2, the atmosphere pollution such as dust, and reduce waste water yield and discharge capacity；Have the disadvantage that KOH media are expensive, and
The mass ratio of KOH and slag is 3:1 to 5:1st, reaction alkali concn is 60%-90%, then the KOH media being lost are more, causes life
Produce high expensive, the reduction of product benefit.However, there are no the relevant report that vanadium slag sodium carbonate direct weighting leaches vanadium extraction at present.
CN102094123A proposes a kind of method that sodium hydroxide medium of use high concentration extracts vanadium from v-bearing steel slag,
This method reaction temperature be 180-240 DEG C, wet method vanadium extraction, during without waste gas, dust pollution；Have the disadvantage that alkali concn is higher, alkali
Spend for 65-90%, then the heat of evaporation and concentration needs when causing the medium circulation to utilize is higher, then production cost is higher, and end
Remaining V amounts are higher in slag, and leaching rate is not high, and V content is 0.3-0.5% in finishing slag.
At present, it there is no the report that v-bearing steel slag is leached on sodium carbonate direct weighting.
