比利时Hydrometal工厂有色金属的回收利用

Hydrometal工厂可以提供完善的技术用于将已经废弃的金属废料再次引入到工业循环阶段,因此,不但节约了资源和能源,而且也更加环保。本文讨论的两个研究案例是关于比利时的一套完整的湿法冶金循环利用装置。(1)在锌泥的工艺处理过程中,残留的低质酸及碱通过几个连续的选择性浸出沉淀工序可以用来生产铜、镍、钴及锌精矿。(2)对铜阳极泥进行处理,回收其中的贵金属成分。根据铜阳极泥的成分,可以生产出单独的或者混合的铜、铋、碲、硒和银/贵金属精矿。

Recycling of non-ferrous metals at Hydrometal,Belgium

Hydrometal provides an adequate technology to reintroduce otherwise lost metal units into the industrial cycle,thereby saving resources and energy,while keeping the environment cleaner.Two case studies at an integrated hydrometallurgical recycling facility (Hydrometal) in Belgium are discussed:(1) Residual low quality acid and caustic are used in the processing of zinc industry cements to produce copper,nickel,cobalt and zinc concentrates by several consecutive selective leach-precipitation processes.(2) Co...
