Description
Technical field
The invention belongs to the recycling of tin-coated copper material, the isolating spray detin of particularly zinc-plated copper billet material copper tin method and apparatus.
Background technology
The zinc-plated copper strips of a large amount of uses of telecommunications industry and solar cell, conflux band and welding to the processing of this part zinc-plated copper billet material, except that a part is used to produce the bell metal, utilize occasion for other, all require to remove the tin coating on the copper cash.Tin content has very high recovery value more than 8% in the zinc-plated copper strips.
At present, main both at home and abroad pyrogenic process, pyrogenic process electrolysis process, electrochemical method and the chemical process recovery WTC of adopting.Chinese invention patent 95111809.9 utilizes pyrogenic process in the particular melt medium, to reclaim tin, reaches the isolating effect of copper tin.But exist energy consumption high, separate problems such as not thorough.The pyrogenic process electrolysis process is that waste material is smelted into the electrolysis copper coin, reaches separating copper tin effect through electrolysis, and this method exists energy consumption high, and operational path is long, the shortcoming that production cost is high.Electrochemical method can not etch copper matrix, and can reclaim spongy tin, and the melting removal of impurities of washing back can obtain 99.9% tin, but since in the WTC tin content differ, be difficult to control electrochemistry and reclaim technology, be difficult to scale operation.Part enterprise places technical hydrochloric acid to waste and old WTC; Utilize oxygenant separating copper tin such as iron trichloride or ydrogen peroxide 50, reach the effect that reclaims copper, but this method subsequent treatment cost is high; There is certain corrosion in copper, and in the follow-up immersion liquid copper, tin and iron separate purification ratio the difficulty.
Chinese invention patent 200910090636.9 proposes copper sulfate displacement-heap leaching method and reclaims the copper tin in the waste and old WTC, solve WTC suitability for industrialized production problem, but dump leaching speed is slower, and efficiency ratio is lower.Chinese invention patent 201010601227.1 proposes to adopt and gets rid of the copper tin separation that soaking technology is realized tin-coated copper rice, but because zinc-plated copper billet material lumpiness is bigger, is not suitable in getting rid of bath unit, carrying out detin.The present invention will adopt the method and apparatus of spray detin that zinc-plated copper billet material copper tin is effectively separated, and can realize continuity production, and extraction time is short, and the tin decreasing ratio is high.
