Recovery of precious metals and copper from copper/gold ores using resin technology

机译:使用树脂技术从铜/金矿石中回收贵金属和铜

摘要

A process for the selective recovery of precious metals from a medium loaded with precious metals and base metals. The selective recovery of precious metals is achieved by exposing the medium to an aqueous solution containing a complex of formula MX2-, wherein M is a metal of group IB or IIB of the Periodic Table of Elements, and X is a monovalent radical. A second invention relates to the removal of copper from the medium whereby elution of copper is achieved by exposing the medium to an aqueous solution capable of oxidising Cu(I) to Cu(II) whilst not eluting precious metals from the medium.
