前言同和矿业公司小坂矿山月产电铜约四千吨。电解槽480个,其中种板槽25个,造酸槽8个。造酸槽是每两个槽串联成为4组,造酸槽的给液是铜电解液和提取硫酸铜后的溶液。造酸尾液送到硫化氢净液工序使砷、锑、铋成硫化物沉淀。这时,残留在尾液中的铜也同时变成硫化物沉淀。为了除去溶液中的铜,采用电解法比用硫化氢便宜。因此造酸槽尾液的含铜必须保持低浓度而稳定。尾液铜浓度的变化不仅会使成本 Foreword With the mining company Osan monthly production of about 400 tons of copper. 480 electrolytic cells, of which 25 kinds of plank tank, acid tank 8. Acid tank is connected in tandem into two groups of four groups, the acid tank is the copper electrolyte and copper sulfate extraction solution. Sour acid tail liquid sent to the hydrogen sulfide process so that arsenic, antimony, bismuth sulfide precipitation. At this time, the remaining copper in the tailings also becomes a sulfide precipitate. In order to remove the copper in the solution, electrolysis is cheaper than using hydrogen sulfide. Therefore, acid bath tails liquid copper must be kept low concentration and stability. The copper concentration of the tail fluid will not only make the cost change
