Abstract

The addition of NaCl in the ammonium persulfate-APS (as an oxidant) leaching was investigated. APS has some advantages compared with conventional oxidants and its standard redox potential (E°) is 2.0 V. Effect of six parameters such as NaCl concentration, APS concentration, temperature, time, liquid–solid ration (L/S), and stirring speed on the leaching behavior was studied. Results showed that metals extraction increased with increasing of NaCl concentration, APS concentration, leaching temperature (up to 333 K), and L/S ratio. During oxidative leaching of sulfide minerals, the occurrence of elemental sulfur layer on particle surface is known as primary problem that causes low metal extraction. According to the results, the passivation effect of sulfur layer and low dissolution problems can be eliminated in the presence of chloride ions. Copper and iron extraction yields were obtained as 75% and 80%, respectively under leaching conditions as follows: APS concentration 250 g/L; NaCl concentration 150 g/L; time 180 min; temperature 333 K; stirring speed 400 r/min; and L/S 250 mL/g.

摘要

本文研究了在过硫酸铵-APS 作为氧化剂中添加 NaCl 对黄铜矿浸出行为的影响。 APS 与传统氧化剂相比有许多优势, 其标准氧化还原电位为 2.0 V。 研究了 6 个参数, 包括 NaCl 浓度, APS 浓度, 温度, 时间, 液固比, 搅拌速率对浸出行为的影响, 结果表明金属的提取率随 NaCl 浓度, APS 浓度, 浸出温度和液固比的增加而增加。 在硫化物矿物的氧化浸出过程中, 在颗粒表面出现的硫元素层会降低金属的提取率。 本研究结果表明, 由于 Cl 离子的存在, 硫元素层的钝化和低溶解度问题都得到消除。 在 APS 浓度为 250 g/L, NaCl 浓度为 150 g/L, 时间为 180 min, 温度为 333 K, 搅拌速率为 400 r/min 及液固比为 250 mL/g 的条件下, 铜和铁的提取率分别为 75% 和 80%。
