摘要
加压浸出属于湿法冶金过程强化技术,与常规湿法浸出相比,具有反应速度快、浸出率高、环境友好等优点,自1887年工业化以来,已在铀、铜、铝、锌、镍、钴、钼、黄金等行业得到推广应用。总结了加压浸出技术在稀贵金属行业的应用和研究现状,包括钼、黄金和铂族金属等原生矿产,以及铜阳极泥、镓锗富集渣、含砷固废等二次资源。在总结归纳技术现状基础上,对加压浸出技术在稀贵金属行业未来发展趋势进行了展望。
Compared with traditional hydrometallurgy process,pressure leaching technology is a strengthening hydrometallurgical process with the advantages of fast reaction speed,high metal leaching rate and environmental friendly.Since industrialization in 1887,it has been widely used in uranium,copper,aluminum,zinc,nickel,cobalt,molybdenum,gold and other industries.In this paper,application and research status of pressure leaching technology in rare and precious metals industry were summarized,including primary minerals such as molybdenum,gold and PGMs,as well as secondary resources such as copper anode slime,scattered metal enrichment and arsenic-containing solid wastes.On the basis of summarization,the future development trend of pressure leaching technology in rare and precious metal industry is prospected.
