分子识别技术在铜工业应用中的最新进展

分子识别技术(MRT)——一种高选择性分离技术的使用,对于铜的电解精炼和电积系统中的多种阳离子和阴离子,证明是一种成本低、效益高、环保好的处理技术。这些离子包括重金属、过渡金属、贵金属、卤化物、碱金属/碱土金属离子。本文总结了分子识别技术(MRT)在各种令人感兴趣的领域中的应用:从铜阳极泥中回收和精炼铂族金属,从矿山酸性排水中回收铜;从铜电解精炼和电积过程中提取Bi、Sb和Cl。

Recent advances in the application of molecular recognition technology (MRT)in the copper industry

The use of MRT,a highly selective separations technology,has been demonstrated to be a cost effective, efficient,and environmentally-sound treatment for a wide range of cations and anions that are commonly found in copper electrorefining and electrowinning circuits,as well as in environmental treatment operations.These include heavy and transition metals,precious metals,halides and alkali/alkaline earths.This paper will review a number of areas of interest including:recovery and refining of platinum group metals from copper anode slimes,recovery of copper from acid mine drainage streams,extraction of Bi,Sb and Cl from copper electrorefining and eleetrowinning circuits.
