Method for separating and isolating precious metals from non precious metals dissolved in solutions

Method for separating and isolating precious metals from non precious metals dissolved in solutions

A method for separating gold and/or silver from copper or other contaminant metals is provided in which a suitable filter membrane (64), particularly a nanofilter, is used to form a retentate (134) containing most of the multivalent metal cyanide complexes and a permeate (135) containing most of the...

description A method for separating gold and/or silver from copper or other contaminant metals is provided in which a suitable filter membrane (64), particularly a nanofilter, is used to form a retentate (134) containing most of the multivalent metal cyanide complexes and a permeate (135) containing most of the precious metal cyanide complexes. The process is particularly applicable to the recovery of gold and/or silver from ores containing these metals and one or more contaminant metals. The precious metal can thereafter be recovered from the permeate (135) and the metal in the multivalent metal cyanide complex from the retentate (134).
