Manufacturing of inorganic chloride compound as well as inorganic copper compound from the simultaneous treatment of cupric chloride, cupric sulphate and cupric ammonium chloride spent etching solution in a single process, and the inorganic chloride compound and the inorganic copper compound using the same

摘要

The present invention is an acidic (hydrochloric acid, sex, sulfuric acid) is a technique for the simultaneous production of such waste with a basic (ammonia), and a waste solution composed mainly of copper and ammonium simultaneously processed in a single process, inorganic chlorine compounds, and copper (Cu) compound. ; Production of motion extraction and ammonium chloride (yeomam) is as follows. ; _{Cu (NH 3) 4 Cl 2} (aq) + CuCl 2 (aq) + 4RH (org) → 2CuR 2 (org) + 4NH 4 Cl (aq) ( liquid yeomam) (R: an organic solvent) ; Production of motion and back-extraction of copper sulfate (copper compound) is as follows. ; _{CuR 2 (org) + H 2} SO 4 (aq) + CuSO 4 (aq) → 2RH (org) + 2CuSO 4 (aq) ( liquid copper sulfate) ; (R: an organic solvent) ; Yeomam the liquid is in the solvent extraction process, the liquid of copper sulfate are respectively produced in the solvent extraction process station, when the separation and drying of this solid phase the liquid phase is produced yeomam and copper sulfate. ; Sanseongdong waste liquid, waste liquid basic copper, inorganic chlorine compounds, a waste solution, extracted huaek, raffinate (raffinate), yeomam, such inorganic compounds, copper sulfate, organic solvent extraction, extraction station
