Eliminating Copper from Gold Ore

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper

Diethyldithiocarbamate (DDTC) extraction of copper(II)

Summary The extraction behaviour of copper(II) and iron(III) was studied in the presence of humic substances (humic and fulvic acids) by using DDTC and chloroform. Copper humic complexes were nearly completely extracted over the pH range 39, indicating that DDTC reacted with copper more strongly than humic substances.
