Description
Technical field
The present invention relates to a kind of methods that silver is extracted from vulcanization silver-bearing copper, belong to technical field of chemistry and chemical engineering.
Background technique
The electric conductivity and thermal conductivity of silver are highest in all metals, while having excellent ductility and plastic
Property, be commonly used to the high physical apparatus element of production sensitivity, electronics, computer, communication, military project, aerospace, video display,
Etc. industries be widely used, it has also become industry and national defense construction in indispensable important materials.
The method of traditional extraction silver is to make solvent with the aqueous solution of alkali metal cyanide, silver is extracted from argentiferous material, so
Silver is recycled from the solution of argentiferous afterwards.The method that silver is recycled from Cyanide Leaching liquid is more mature, there is metal replacement method, active carbon
Absorption method, ion-exchange-resin process, strike etc..But cyanide is deadly poisonous compound, and transport is difficult, and it is at high cost, to ring
Border is unfriendly, and the remaining slag of cyaniding processing argentiferous material has been divided as danger wastes, and harmless treatment cost is huge.
Currently, how green, high efficiency extraction silver is domestic and international the problem of relatively paying close attention to.
Summary of the invention
The object of the present invention is to provide a kind of methods that silver is extracted from vulcanization silver-bearing copper, and this method is with cupric thiosulfate Cu
(S2O3)n -2n+1Solution, vulcanization silver-bearing copper (CuAgS) and zinc powder (Zn) are starting material, obtain silver-colored simple substance (Ag) product by reaction,
Silver dissolution rate of the invention is high, and the rate of recovery is high.
The technical solution of the method for the present invention is as follows: first vacuumizing thiosulfuric acid copper solution or inflated with nitrogen removing is therein
Dissolved oxygen obtains the solution containing silver thiosulfate then vulcanization silver-bearing copper and thiosulfuric acid copper solution hybrid reaction, then with through dilute
Zinc powder after sulfuric acid activated displaces silver-colored simple substance from silver thiosulfate solution.
Specific step is as follows for the method for the present invention:
(1) thiosulfuric acid copper solution is vacuumized or inflated with nitrogen is to remove dissolved oxygen therein；
(2) at 1~60 DEG C, silver-bearing copper will be vulcanized with step (1) except the thiosulfuric acid copper solution after dissolved oxygen mixes, and adjust
The pH of whole mixed solution is 2~12, is then stirred to react 10min~12h, then mixed solution after reaction is filtered, and is removed
Insoluble matter obtains silver thiosulfate solution；
(3) pH for adjusting silver thiosulfate solution is 2~12, is then added into silver thiosulfate solution living through dilute sulfuric acid
Metal zinc after change is replaced to obtain silver-colored simple substance.
Except dissolved oxygen concentration is less than 2mg/L in thiosulfuric acid copper solution after dissolved oxygen in step (1).
Silver-bearing copper will be vulcanized in the step (2) and concentration is 0.05~0.5mol/L except the thiosulfuric acid after dissolved oxygen
Copper solution mixing.
The molar ratio of vulcanization silver-bearing copper and thiosulfuric acid copper solution is 0.1~0.5 in the step (2).
The molar ratio of metal zinc and silver ion in silver thiosulfate solution is 2:1~6:1 in the step (3).
The concentration of the dilute sulfuric acid of activated metal zinc powder is 4 × 10 in step (3)-6~4 × 10-5mol/L。
The principle of the present invention is: the solubility product constant of cuprous sulfide is less than the solubility product constant of vulcanization silver-bearing copper, and Ag
(S2O3)n -2n+1Stability constant compared with Cu (S2O3)n -2n+1Stability constant it is bigger, vulcanize silver-bearing copper (CuAgS) in cupric thiosulfate Cu
(S2O3)n -2n+1Smaller cuprous sulfide (the Cu of solubility product can be generated in (n=1~3) solution2S) compound and more stable Ag
(S2O3)n -2n+1(n=1~3)；The present invention be exactly based on principles above from vulcanization silver-bearing copper in extract silver, then with activate after zinc powder
Displacement recycling silver.
The present invention vacuumizes thiosulfuric acid copper solution or the purpose of inflated with nitrogen is the dissolved oxygen removed in solution, prevents sulphur
The degradation of thiosulfuric acid copper avoids silver sulfide copper surface passivation caused by catabolite, while improving the reaction activity of solution, promotes
Reaction carries out.
The activation of zinc powder dilute sulfuric acid is to improve replacement rate and displacement to dissolve the micro oxide in its surface by the present invention
Efficiency.
Its reaction route is as follows:
CuAgS+Cu(S2O3)n -2n+1=Ag (S2O3)n -2n+1+Cu2S↓
Zn+Ag(S2O3)n -2n+1=Ag ↓+Zn2++2S2O3 2-+S4O6 2-
Zn+2Ag(S2O3)n -2n+1=2Ag ↓+Zn (S2O3)2 2-
Compared with prior art, the beneficial effects of the present invention are:
(1) the method for the present invention is easy to operate, silver-colored dissolution rate high (> 95%), the rate of recovery are high (> 99%).
(2) inefficient, pollution environment problem that the present invention overcomes general extraction methods, the method for the present invention are green
Color, efficient, application value height.
