Abstract
The invention provides a process for extracting vanadium from vanadium-containing iron ore concentrate pellets which comprises, charging right amount of sodium salt into iron concentrate powder, carrying out water dipping treatment to dissolve the soluble sodium vanadate into water, charging sulphuric acid into sodium vanadate solution, concentrating and mixing, agitating, precipitating vanadium pentoxide, filtering and drying into powdery or tablet form vanadium pentoxide end product.
Description
Technical field
The invention belongs to the chemical metallurgy technical field.
Background technology
At present, the technology of extraction vanadium is to contain vanadium iron fine ore sintering, to smelt into vanadium-bearing hot metal from contain the vanadium iron ore deposit; The v element that blows again in the vanadium-bearing hot metal oxidation molten iron obtains vanadium slag.Again vanadium slag is handled and obtained the Vanadium Pentoxide in FLAKES product.This method technical process is long, and is many through ironmaking and two operation losses of blowing vanadium slag v element, so the rate of recovery of vanadium is lower.
Summary of the invention
The present invention becomes the sodium pelletizing with containing the smart powder of vanadium iron with sodium salt (sodium sulfate, yellow soda ash etc.) fine powder mixed pelletizing, roasting; Sodium pelletizing process water logging processing is dissolved into the solubility vanadic acid sodium in the pelletizing and makes sodium vanadate solution in the water; In sodium vanadate solution, add sulfuric acid precipitation and go out the Vanadium Pentoxide in FLAKES product.Present method technical process is short; The vanadium loss is few, the comprehensive recovery height.
Specific implementation method
The sodium salt mixed pelletizing that 200 orders contain vanadium iron fine ore and corresponding granularity and weight, granularity 10-20 millimeter will be born.Pelletizing is through shaft furnace or return brickkiln roasting, controlled temperature 600-1300 ℃; Time is 3-5 hour, makes the vanadium in the pelletizing be converted into solubility vanadic acid sodium to greatest extent.
The pelletizing that roasting is good is immersed in and makes in the water that solubility vanadic acid sodium is dissolved in the water in the pelletizing.For dissolving is accelerated, more than the heated solution to 90 ℃ and add strong mixing.Solution will repeatedly soak pelletizing and every batch of pelletizing is repeatedly handled by solution soaking.Make solution contain that vanadium concentration constantly increases and in the pelletizing vanadiumcontent constantly reduce; The leaching yield of vanadium reaches more than 85%.Leach qualified solution and send the precipitation operation; Pelletizing after the leaching is still as iron-smelting raw material.
Qualified sodium vanadate solution is delivered in the settling tank, adds the sulfuric acid of respective amount.Heated solution also stirs, and impels reaction precipitation to go out Vanadium Pentoxide in FLAKES.The powdery finished product is made in mud shape Vanadium Pentoxide in FLAKES filter-press dehydration oven dry or fusing is cast into the piece of Vanadium finished product.
Claims (4)
1, a kind of vanadium iron concentrate pelletizing extraction vanadium method that contains is characterized in that, will contain the vanadium iron fine ore and make pelletizing, roasting with addition of the sodium salt powder; By the water logging pelletizing solubility vanadic acid sodium in the pelletizing is dissolved into and obtains sodium vanadate solution in the water; Sulfuric acid joined obtain the Vanadium Pentoxide in FLAKES solid sediment in the sodium vanadate solution.
2, the vanadium iron concentrate pelletizing extraction vanadium method that contains according to claim 1 is characterized in that, sodium salt in the pelletizing (sodium sulfate, yellow soda ash etc.) add-on is determined according to containing vanadium iron fine ore composition; Pellet roasting is at shaft furnace or return in the brickkiln and carry out, and the roasting process temperature is controlled at 600-1300 ℃, roasting time and was controlled at 2-5 hour.
According to claim 1 and the 2 described vanadium iron concentrate pelletizing extraction vanadium methods that contain, it is characterized in that 3, the pelletizing that roasting is good will heat, stir, control immersion total time more than 2 hours in the water logging process, and repeatedly change the sodium vanadate solution that leaches.
According to the described vanadium iron concentrate pelletizing extraction vanadium method that contains of claim 1-3, it is characterized in that 4, control adds sulfuric acid amount according to sodium vanadate solution concentration during precipitation; And heating, stir and sufficient sedimentation time arranged.
