【摘要】 研究用三乙醇胺电解法从废杜美丝中回收制取铜粉的工艺．铜在阳极电解退除，并以铜粉的形式在阴极沉淀回收．实验中确定最佳工艺条件为：铜配离子浓度为０．１５７ｍｏｌ·Ｌ－１，游离三乙醇胺浓度为０．６４８ｍｏｌ·Ｌ－１，ｐＨ值７．００，阴极电流密度１４Ａ·ｄｍ－２，电解温度４０℃．在此条件及基体金属不受腐蚀下制得的铜粉，粒径小于７４μｍ的可达９０％；阴极的电流效率达９１％；平均槽电压０．９７５Ｖ；电能消耗９００ｋＷ·ｈ／ｔ更多还原

【Abstract】 In this paper,an electrolytic process has been given for recovering copper from waste dume wire.In this process,copper powder was eletrodeposited on the cathode with electrolytic removal of copper from the anode in the same time.The electrolytic process was carried out under the following optimum technological conditions ,i.e.concentration of [Cu(tea)(OH)]+0157mol·L-1;concentration of triethanolamine 0648mol·L-1;pH 700;current density 14A·dm-2;solution temperature 40℃.The current efficiency is 91%; the specific electric energy consumption is 900kW·h·t-1;the copper powders made are smaller than 74 μm by 90% under such conditions,while the primary metals are not eroded.更多还原
