Description
Technical field
The invention belongs to vanadium field of chemical metallurgical technology, and in particular to a kind of production method of clean vanadium liquid.
Background technology
Vanadic anhydride production conventional method be vanadium slag sodium roasting-vanadium liquid purification-ammonium salt precipitation method, wherein 65% with
On vanadium product come from the method.So-called vanadium liquid purification, exactly removing influences the impurity element of precipitation effect in vanadium liquid, influence
The principal element of vanadium liquid precipitation effect has impurity element（Silicon, phosphorus, iron, aluminium）And suspension in stoste.According to raw material vanadium slag feature,
Vanadium liquid impurity situation Si contents are between 600mg/L to 800mg/L, and P content is between 80mg/L to 100mg/L.
At present, removal of impurities is carried out in 25g/L~30g/L vanadium solutions to vanadium concentration, using traditional vanadium liquid impurity removal process：It is a kind of
It is regulation vanadium liquid pH, silicon, the phosphorus added into vanadium liquid in aluminum sulfate solution, co-precipitation liquid phase；Another is the pH for controlling vanadium liquid,
Calcium or magnesia additives are added into vanadium liquid, silicon, phosphorus in liquid phase is removed.Qualified solution impurity after domestic vanadium industry removal of impurities contains
Measure and be：Silicon is less than 500mg/L, and phosphorus content is less than 15mg/L.
The ammonium salt precipitation method have two kinds：A kind of is that the pH value of the solution containing pentavalent vanadium first is adjusted into 8.5~9.5, then by molten
V in liquid2O5With the mass ratio 1 of ammonium salt:1.3~1.5 add ammonium salt Precipitation ammonium metavanadate；Another reconciled using substep
The pH value of solution adds ammonium salt Precipitation ammonium poly-vanadate to 1.5~2.5, after obtained ammonium metavanadate or ammonium poly-vanadate are passed through
Calcining obtains vanadic anhydride.Because the impurity that precipitation process is carried secretly does not have suitable method to be gone in follow-up process
Remove, so the vanadic anhydride impurity content obtained using process above is higher, the grade of vanadic anhydride only has 98% left side
The right side, containing impurity elements such as Fe, Al, K, Na, Ca, Mg, Si, P, S and As, it is difficult to meet multiple fields to purity of vanadium pentoxide
Requirement.
As can be seen here, using the method for purification is precipitated, it is necessary to add the cleanser of a large amount of calcics, magnesium, aluminium or sodium plasma, produce
Cost is higher and easily causes that the element single index of these in product is exceeded, so the vanadium product purity that production is obtained is not high,
98.5% or so.
