分子识别技术在铜工业应用中的最新进展

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

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。

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 electrowinning circuits.
