30万吨/年电铜的铜电解精炼车间工艺设计
设计总说明
铜电解精炼过程,主要是在直流电的作用下,铜在阳极上失去电子后以铜离子的形态溶解,而铜离子在阴极上得到电子以金属铜的形态析出的过程。目前世界铜冶炼厂使用的主要熔炼工艺为闪速熔炼和熔池熔炼,其中熔池熔炼包括诺兰达连续炼铜法、艾萨熔炼法、瓦纽科夫法。
本设计为年产30万吨电铜的铜电解精炼车间,铜的电解精炼是以火法精炼产出的精铜为阳极,以电解产出的薄铜(始极片)作阴极,以硫酸铜和硫酸的水溶液作电解液。在直流电的作用下,阳极铜进行电化学溶解,纯铜在阴极中沉积,杂质则进入阳极泥和电解液中,从而实现了铜与杂质的分离,确定了铜电解过程中的主要技术经济指标。本设计还进行了物料平衡、热平衡、水平衡、主要设备及辅助设备的计算选择。进一步提高铜电解精炼的技术水平,从而达到对铜电解精炼技术有更深刻了解的目的。

Design Description
The copper electrolysis fining process is mainly under the direct current function,copper loses the electron after the anode by cupric ion shape dissolution,but the cupric ion obtains the electron on the negative pole by the metal copper shape separation process.At present the world copper refinery use main smelting craft to dodge the fast smelting and the molten bath smelts,the molten bath smelts including the Landa continual copper smelting,Isa smelts,Niu Shinao smelts.
Originally designed to produce per 300,000 the first electrolytic copper refine the work shop,refining the precise copper produced electrolytically and concisely as the positive pole with fire law of copper,take copper sulfic acid and aqueous solution of the sulfuric acid as the electrolytic liquid very much with the electrolytic thin copper beginning that produces.Under the funcition of the direct current,positive pole copper carries on electrochemistry to dissolve,pure copper is deposited in the negative pole,the impurity is entered in positive pole mud and electrolytic liquid,thus realized the separation of the copper and impurity,have confirmed the main technical and economic index in the
electrolytic course of copper.Have originally designed and also carried on supplies equilibrating,calculation and choice of the thermal balance,horizontal weighing apparatus,capital equipment and auxiliary equipment. Further improve the standard of the electrolytic refining and reached for the refinement of the electrolytic technology is a profound understanding of purpose.
