Description

A kind of zinc-plated isolating spraying method of copper billet material copper tin and device
?
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 tinned wird of adopting.Chinese invention patent 95111809.9 utilizes pyrogenic process to reclaim tin in the particular melt medium, reaches the isolating effect of copper tin.But there is the energy consumption height, separates 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 by electrolysis, and there is the energy consumption height in this method, 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 tinned wird 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 tinned wird, utilize oxygenant separating copper tin such as iron trichloride or hydrogen peroxide, reach the effect that reclaims copper, but this method subsequent treatment cost height, 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 proposition copper sulfate displacement-heap leaching method reclaim the copper tin in the waste and old tinned wird, solve tinned wird suitability for industrialized production problem, but dump leaching speed are 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 for carrying out detin in getting rid of bath unit.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, tin decreasing ratio height.
Chinese patent application number: in 201010279564.5 " a kind of method and apparatus of tin-coated copper rice Separation and Recovery metal copper tin ", the detin process is described in detail, quoted in full at this, among the application, the reagent of detin process is identical with above-mentioned application with consumption.
