一、前言用电积法生产锌,必须对净液和电积条件严格管理和控制。例如日本秋田冶炼厂在净液工序采用四段连续作业,进行深度净化,不仅对电积液成分及温度的管理十分严格,而且对电积设备和阳极也不断改进,该厂月产电锌7200吨,电锌品位达(%):Zn I. Preface Production of zinc by electrowinning method requires strict management and control over the conditions of net liquid and electrowinning. For example, the Japanese Akita smelter in the net liquid process using four continuous operation, the depth of purification, not only for the electro-hydraulic composition and temperature management is very strict, but also for the electrowinning equipment and anode also continue to improve, the plant monthly production of zinc 7200 Ton, electric zinc grade (%): Zn
