Abstract
The present invention relates to a kind of indium and extract indium, zinc separation and recovery method in displaced liquid, use the principle that indium, zinc hydrolysis pH value is different, directly separately extract after indium, zinc solute being separated, operation is simple, low cost, indium recovery are high, and does not bring chlorine element into.
Description
Technical field
The present invention relates to a kind of preparation method of nano material, extract indium in displaced liquid, zinc separation particularly to a kind of indium
Recovery method.
Background technology
Indium is a kind of expensive dissipated metal, with the association such as zinc ore, copper mine, owing to its content is low, be worth height, is having
Color smelting industry takes synthetical recovery mode to extract.General employing P204 extraction in zinc metallurgical process is extracted in the smelting of indium
Separating with zinc, be then enriched with concentrated hydrochloric acid back extraction, strip liquor zinc displaces sponge indium, is able to separating-purifying.When putting
When changing in rear liquid indium content less than 0.5g/L, the method that zinc can not have been used to replace carries out separating, and existing general method is
It is transferred to displaced liquid carry out containing the leaching section of indium, zinc material leaching, being enriched with, although so can reach to reclaim valuable metal
Indium, the purpose of zinc, but add the technological process that indium reclaims, cause high expensive, the response rate to decline, and displaced liquid is chloride
Ion is the highest, and these chloride ion enter into zinc abstraction system, meeting severe corrosion equipment, and have serious to the amount of electrolyte of zinc
Negative effect, causes zinc ingot metal lead content higher, and the trade mark declines.How processing indium displaced liquid is the skill that indium reclaims and purifies
An art difficult problem.Prior art has following defects that
1. indium displaced liquid directly proceeds to indium, zinc material leaches operation, adds the recovery process flow process of indium, adds and produce into
This, and reduce the response rate of indium；
2. indium displaced liquid directly proceeds to indium, zinc material leaches operation, introduces a large amount of chloride ion, and heavy corrosion produces equipment；
3. due to the existence of chloride ion, cause the corrosion of zinc anode plate, cause impurity lead in zinc ingot metal higher, affect the matter of zinc ingot metal
Amount.
Summary of the invention
It is an object of the invention to provide a kind of principle utilizing indium, zinc hydrolysis pH value different, place simple, convenient to operate
The technical method of reason indium displaced liquid, solves the leaching of prior art, the introducing chloride ion entrance of Enrichment Indium recovery process flow process
The adverse effect of zinc abstraction system, and the problem that complex procedures, cost are high, indium recovery is low.
The technical solution used in the present invention is: a kind of indium extracts after displacement indium, zinc separation and recovery method in solution, including such as
Lower step: the pH=4.0-4.5 of A. alkali liquor regulation displaced liquid；B. filtering separation, gained filtering residue is indium hydroxide, hydrogen-oxygen
Change indium and be directly dissolved in indium strip liquor, carry out displacement and carry indium；C. the filtrate after filtering indium presses the ratios with water dilution of 1:3-5, then
Add phenolphthalein indicator, the sodium hydroxide solution regulation solution ph of continuation 100g/L, until the micro-redness of solution；D. filter
Separating, gained filtering residue is zinc hydroxide, and zinc hydroxide enters zinc recovering system；E. filter the filtrate after zinc and use vacuum evaporation
Reclaim sodium chloride.
The further technical scheme of the present invention is: alkali liquor described in step A is the sodium hydroxide solution of 100g/L.
The further technical scheme of the present invention is: alkali liquor described in step A is ammonia, potassium hydroxide, ammonium carbonate, carbonic acid
One in sodium, potassium carbonate, ammonium hydrogen carbonate, sodium bicarbonate, potassium bicarbonate.
The invention has the beneficial effects as follows: owing to using indium, zinc to hydrolyze the principle that pH value is different, after indium, zinc solute are separated
Directly separately extracting, operation is simple, low cost, indium recovery are high, and does not bring chlorine element into.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described further.
A kind of indium extracts after displacement indium, zinc separation and recovery method in solution, comprises the steps:
A. with the pH=4.0-4.5 of the sodium hydroxide solution regulation displaced liquid of 100g/L.The pH of the indium displaced liquid that concentration is relatively low
When value reaches 3.6, indium hydroxide precipitation starts to separate out, and precipitates completely when pH value reaches 4.5, and now zinc remains entirely in solution
In, indium and zinc efficiently separate.Sodium hydroxide in step A, can use ammonia, potassium hydroxide, ammonium carbonate, sodium carbonate, potassium carbonate,
A kind of replacement in ammonium hydrogen carbonate, sodium bicarbonate, potassium bicarbonate.
B. filtering separation, gained filtering residue is indium hydroxide, and indium hydroxide can be directly dissolved in indium strip liquor, carries out displacement and carries
Indium.Indium hydroxide after separation is directly dissolved in indium strip liquor, and the indium that precipitation reclaims decreases the technique of extraction and back extraction, both
Shorten technological process, improve again the response rate.
C. the filtrate after filtering indium presses the ratios with water dilution of 1:3-5, is subsequently adding phenolphthalein indicator, continues to use 100g/L
Sodium hydroxide solution regulation solution ph, until the micro-redness of solution.Filtrate to dilute the zinc hydroxide body being because generating
Long-pending bigger, it is beneficial to stir neutralization, zinc ion starts precipitation when pH reaches 5.4, precipitates complete pH and can be increased to 8.0, phenolphthalein
Color change interval be pH=7.4-10.0, alkali liquor little over measure then solution can be by without complexion changed blush, instruction neutralizes terminal, and pH reaches
More than 10.5 can cause zinc hydroxide to redissolve.
D. filtering separation, gained filtering residue is zinc hydroxide, and zinc hydroxide enters zinc recovering system.Zinc hydroxide is as heavy
Precipitation goes out, and efficiently separates with chloride ion, it is to avoid chloride ion enters the harm that zinc abstraction system is brought.
E. the filtrate after filtering zinc can be evaporated in vacuo recovery sodium chloride.Owing to using indium, zinc to hydrolyze the principle that pH value is different,
Directly separately extracting after indium, zinc solute being separated, operation is simple, low cost, indium recovery are high, and does not bring chlorine element into.
The foregoing is only presently preferred embodiments of the present invention, the present invention is only exemplified as kind of a tree, but is not limited to kind of a tree, appoints
What is the need for and want the occasion of one of moisturizing, insulation, weeding function to use, not in order to limit the present invention, all the present invention's
Any amendment, equivalent and the improvement etc. made within spirit and principle, should be included within the scope of the present invention.
