摘 要: 研究了鎳锍選擇性氧化浸出產(chǎn)生的銅渣在硫酸介質(zhì)中氯離子參與下的氧氣氧化浸出。考察和比較了氯化物用量、氧氣流量、硫酸濃度、溫度等因素對(duì)銅和鎳浸出的影響，并討論了其原因。確認(rèn)了在硫酸介質(zhì)中加入少量氯化物即可在常壓下用氧氣有效地浸出主要由輝銅礦或類似的硫化銅礦物組成的銅渣。

Abstract:Leaching of a copper residue，produced by selected oxidation leaching of a nickel matte，in oxygenated sulfuric acid solution with the participation of chloride was investigated. The leaching behaviors of copper and nickel in the copper residue were described. The effects of quantity of chloride，flowrate of oxygen，concentration of sulfuric acid and temperature were discussed as leaching variables. Addition of chloride in small amount into the leach slurry was justified in enhancing copper leaching from the residue.
Key words: copper residue; chloride; oxygen; leaching
