复杂矿石及精矿湿法冶金工艺的进展

由于矿山和冶金工业致力于开发用传统选矿及火法冶金工艺难以处理的矿石,因此,复杂矿石及精矿的湿法冶金处理工艺变得越来越重要。选矿常常面临无法或难以将有价矿物分选为可外销精矿的挑战。湿法冶金利用选择性浸出工艺,常常可以化学分选此类难选矿石。火法处理贱金属精矿投资大,且面临日益严格的环保限制。湿法冶金工艺对于相同的金属产率,通常投资更低,而且避免了与火法冶金相关的烟尘问题,副产品回收的可能性也随着采用湿法冶金处理工艺而提高。以复杂矿石及精矿处理新技术的研发案例作为实例,详细介绍了回收混合硫化矿精矿中铜、钴、铂、钯及金的PLATSOLTM工艺。

Keynote address:hydrometallurgical process development for complex ores and concentrates

Hydrometallurgical processing of complex ores and concentrates is becoming increasingly important as the mining and metallurgical industry seeks to exploit mineral deposits that are difficult to treat using conven tional mineral processing and pyrometallurgical technologies.Mineral processing is often challenged by the difficulty or inability to separate valuable minerals into marketable concentrates.Hydrometallurgical processing,us ing selective leaching technology,can often ' chemically beneficiate ' such...
