Abstract

Описан способ электрорафинирования меди. Способ включает размещение по меньшей мере одного анода из подлежащего рафинированию медного материала в контакте с раствором электролита и размещение по меньшей мере одного катода в контакте с этим раствором электролита. Анод и катод электрически соединяют с источником электроэнергии и осуществляют работу источника в условиях контролируемого потенциала. Электрический потенциал на катоде составляет от -0,30 до -0,55 В по отношению к медному материалу на аноде, вызывая тем самым осаждение электрорафинированной меди на катоде. Способ также включает потенциостатический импульсный электролиз (РРЕ) и периодическое обращение потенциала (PPR), чтобы получить медный осадок с контролируемой структурой, например, по шероховатости или пористости. Описано также устройство для осуществления электролиза с контролируемым потенциалом.A method for the electrorefining of copper is described. The method includes placing at least one anode of a copper material to be refined in contact with an electrolyte solution and placing at least one cathode in contact with this electrolyte solution. The anode and cathode are electrically connected to a power source and the source operates under controlled potential conditions. The electrical potential at the cathode is -0.30 to -0.55 V with respect to the copper material at the anode, thereby causing electrorefined copper to be deposited on the cathode. The method also includes potentiostatic pulsed electrolysis (PPE) and periodic potential reversal (PPR) to obtain a copper deposit with a controlled structure, such as roughness or porosity. A device for carrying out electrolysis with a controlled potential is also described.
