Abstract
The invention discloses a kind of method reclaiming copper from Coppered Steel Wire, the method adopts the mixing solutions of ammoniacal liquor and ammonium sulfate as leaching agent, and pass into air as oxygenant, optionally leach the copper in Coppered Steel Wire, obtain the leach liquor of cupric, adopt P507 as extraction agent the leach liquor obtained, and use dilution heat of sulfuric acid back extraction, obtain the copper-bath of high density, then evaporative crystallization, obtain cupric sulfate pentahydrate product.In extraction process of the present invention, raffinate is the mixed solution of ammoniacal liquor and ammonium sulfate, can be back to the leaching process of copper coated iron wire; In evaporative crystallization copper sulfate process, crystalline mother solution can be used as reverse-extraction agent and is back to solvent extraction step; Therefore, whole technical process can realize closed cycle, avoids " the three wastes " pollution.In addition, this technique also has that production cost is lower, the simple feature of flow process, is easy to realize industrialization.
Description
Technical field
The invention belongs to metal extraction techniques field, particularly relate to a kind of method reclaiming copper from copper plated steel.
Background technology
Coppered Steel Wire adopts the method for electroless plating to plate layer of metal copper, thus there is conductivity and the high frequency performance of the toughness of steel wire and the superior of copper simultaneously, being mainly used in communication and electron trade, is the regeneration product of order wire, cable proprietary material.In use, the copper on surface is easily oxidized thus has a strong impact on its use properties Coppered Steel Wire.Therefore, the every annual meeting of China produces a large amount of waste and old Coppered Steel Wire.In copper coated iron wire, the content of copper higher (being about 6%), has larger economic worth.
At present, the document reclaiming copper from Coppered Steel Wire yet there are no report, but has people to apply for reclaiming the patent of copper from copper facing tin iron pin.In view of, Coppered Steel Wire is comparatively similar with the existing forms of copper in copper facing tin iron pin, has now carried out concise and to the point analysis to the technical characterstic of this patent.The copper of this technique in ammonia solution in Oxidation Leaching copper facing tin iron pin, obtains the ammonia leach liquor of cupric.Then the ammonia solution Direct Electrolysis of cupric is obtained metallic copper.This technology electrolytic copper in ammonia solution, current efficiency is not high, and production cost is higher, and the cathode copper quality product obtained is not high.
Summary of the invention
The object of the present invention is to provide a kind of method reclaiming copper from copper plated steel, be intended to solve the method also not extracting copper at present from copper plated steel, the existing method electrolytic copper in ammonia solution reclaiming copper from copper facing tin iron pin, current efficiency is not high, production cost is higher, and the problem that the cathode copper quality product obtained is not high.
The present invention is achieved in that a kind of method reclaiming copper from copper plated steel comprises the steps:
The mixing solutions of step one, employing ammoniacal liquor and ammonium sulfate as leaching agent, and passes into air as oxygenant, optionally leaches the copper in Coppered Steel Wire, obtains the leach liquor of cupric.
The leach liquor obtained in step 2, step one adopts P507 as extraction agent, and uses dilution heat of sulfuric acid back extraction, obtains the copper-bath of high density.
Step 3, evaporative crystallization, obtain cupric sulfate pentahydrate product.
Further, in extraction process, raffinate is the mixed solution of ammoniacal liquor and ammonium sulfate, can be back to the leaching process of copper coated iron wire.
Further, in evaporative crystallization copper sulfate process, crystalline mother solution can be used as reverse-extraction agent and is back to solvent extraction step.
Further, in leaching process, ammonia concn is 2mol/L, ammonium sulfate concentrations is 1mol/L, liquid-solid ratio is 5:1, extraction time is 2 hours, room temperature, air flow quantity is depending on inventory, and copper leaching rate can to 99%.
Further, in solvent extraction process, extraction agent P507 concentration is 40%, compare that O/A is 1/2, extraction time 5 minutes, reverse-extraction agent sulfuric acid concentration are 2mol/L, back extraction compares that O/A is 3/1, room temperature, and percentage extraction and the back extraction ratio of copper are 99%.
Further, in evaporation and crystal process, the percent crystallization in massecuite controlling copper is about 85%, obtains qualified copper sulfate product.
In extraction process of the present invention, raffinate is the mixed solution of ammoniacal liquor and ammonium sulfate, can be back to the leaching process of copper coated iron wire; In evaporative crystallization copper sulfate process, crystalline mother solution can be used as reverse-extraction agent and is back to solvent extraction step; Therefore, whole technical process can realize closed cycle, avoids " the three wastes " pollution.In addition, this technique also has that production cost is lower, the simple feature of flow process, is easy to realize industrialization.
