The method comprises: (1) adding water to flue dust, leaching out Re in the flue dust to obtain Re-containing leaching solution; (2) adjusting the pH value of the Re-containing leaching solution and tail gas rinsing solution to 5 with ammonium bicarbonate so that Mo, Fe, Cu and Zn ions are converted into hydroxides, separated from Re and precipitated, and filtering to obtain Re-containing solution for extraction; (3) extracting with extractant so that Re enters into the extractant, which is named enriched oil; (4) back-extracting the enriched oil with 3 N ammonia solution so that Re enters into the back extraction solution; (5) adding the back extraction solution into an ion exchange system so that Re is adsorbed onto the resin; (6) preparing 5-10% ammonium thiocyanate solution, adding ammonia solution to adjust the pH value to 8-9, and desorbing Re adsorbed onto the resin to obtain Re-containing desorption solution; (7) evaporating the desorption solution, concentrating, and crystallizing to obtain ammonium perrhenate product.
Description
Technical field
The invention belongs to a kind of separating and extracting method of rhenium, particularly a kind of method of from calcining molybdenum ore concentrate flue dust and leacheate, extracting rhenium.
Background technology
Rhenium is a kind of important industrial raw material, and price is very expensive.At present, people also do not find the suitable mineral of rhenium, and it all is to be present in the molybdenum glance as oligo-elements, or are present in niobite, ytterbite and some magnesium, platinum and the uranium ore as trace substance.At present, rhenium generally is to separate from the roasting gas of producing the generation of molybdenum and copper.The common practice is the solution that obtains rhenium-containing earlier, extracts rhenium by the method for ion-exchange or by method of extraction then.Extract the rhenium alkalescence that acid liquid must be neutralized with the method for ion-exchange, the entrainment loss of rhenium is bigger in N-process, because contain a large amount of sulfate radicals and chlorine root in the solution, sulfate radical and chlorine root are adsorbed onto on the resin, cause the exchange capacity of rhenium little, contain a large amount of impurity in the desorbed solution, need periodic crystallisation, bring difficulty for the purification of rhenium.It is low to extract in its strip liquor of rhenium rhenium-containing concentration with method of extraction, needs could crystallization go out the rehenic acid ammonium through concentrating, and the foreign matter content height, needs just can extract rehenic acid ammonium product through recrystallization repeatedly.Therefore, it is lower to adopt single method to extract the rhenium rate of recovery, and foreign matter content height in the product is difficult to obtain the higher rhenium of purity.
Summary of the invention
The objective of the invention is to solve problems such as the rhenium rate of recovery that prior art exists is low, foreign matter content height, a kind of method of extracting rhenium from calcining molybdenum ore concentrate flue dust and leacheate is provided, improve the rate of recovery of rhenium, obtain highly purified rhenium product.
The present invention is a raw material with the flue dust of calcining molybdenum concentrate generation and the tail gas leacheate of calcining molybdenum concentrate, and its concrete extracting method is:
1, add water in flue dust, liquid-solid ratio is 2～4: 1, and temperature is 80～100 ℃, and the time is 2～3 hours, leaches the rhenium in the flue dust, carries out solid-liquid separation then, filters out solid impurity, obtains the leach liquor of rhenium-containing;
2, with leach liquor and leacheate with the bicarbonate of ammonia PH=5 that neutralizes, make metal ions such as wherein molybdenum, iron, copper, lead form oxyhydroxide, separate with rhenium and precipitate, obtain the preceding liquid of collection of rhenium-containing after filtration;
3, will come together before liquid add in the extraction tank, extract with extraction agent, the organic phase of extraction agent consists of 2.5～5%N235,10～20%TBP, 75～87.5% kerosene, the O/A=1 that is in a ratio of of the extraction agent and the preceding liquid that comes together: 2～4, the residence time is 1～4 minute, make rhenium enter into extraction agent, be called rich oil;
4, rich oil is added in the back extraction groove, with the ammoniacal liquor back extraction of 3N, rich oil and ammoniacal liquor be in a ratio of O/A=2～4: 1, the residence time is 1～4 minute, makes rhenium enter into strip liquor;
5, strip liquor is added in the ion exchange system, ion exchange resin in the ion exchange system is gel type strong basic anion exchange resin 201 * 7, the exchange capacity of resin and rhenium is 50～150mg/ml, rhenium is adsorbed onto on the resin, adsorb surplus liquid rhenium-containing＜0.005g/l, and in turning back to and operation;
6, the ammonium thiocyanate solution of preparation 5～10% adds ammoniacal liquor and is transferred to PH=8～9, resolves the rhenium on the resin, and resolution temperature is 40～60 ℃, and rhenium is resolved from resin, obtains the desorbed solution of rhenium-containing;
7, desorbed solution evaporates under 80～100 ℃ temperature, and condensing crystal promptly obtains the ammonium perrhenate product.
Raffinate is evaporation concentration under 80～100 ℃ temperature, obtains ammonium chloride.
After 1: 9 sulfuric acid cleaned of the oil-poor usefulness regeneration after the back extraction, turn back to reuse in the extraction tank.
The invention has the advantages that, methods such as extraction, ion-exchange and condensing crystal are combined, rhenium in flue dust and the leacheate is carried out comprehensive treating process, it is low to have solved the single method extraction rhenium rate of recovery, problems such as foreign matter content height, can well extract the ammonium perrhenate product, and the purity height of product, grade reaches more than 99%.
