Title: Method for extracting copper, silver and related metals

Abstract

This patent describes a process for selectively extracting precious metal such as silver and gold concurrent with copper extraction from aqueous solutions containing the same. The process utilizes tetrathiamacrocycles and high molecular weight organic acids that exhibit a synergistic relationship when complexing with certain metal ions thereby removing them from ore leach solutions.
