研究山东恒邦冶炼股份有限公司铜的湿法冶炼工艺,发现其存在的问题。通过实验研究,对萃取系统进行改造-增加有机相硫酸洗涤段,洗涤硫酸浓度为10 g/L。新工艺降低了电解液中铁和固体悬浮物含量,使铜的生产成本降低28%。
Research Shandong Dongbang smelting Co., Ltd. copper smelting process and found its existing problems. Through experimental research, the extraction system was modified - adding organic phase sulfuric acid washing section, washing sulfuric acid concentration of 10 g / L. The new process reduces the iron and suspended solids content of the electrolyte, reducing copper production costs by 28%.
