Abstract
Complexing processes between modified diethyldithiocarbamate (DDC) and copper, iron and gold ions in solution, as well as adsorption of modified solution at auriferous pyrite and arsenopyrite are analyzed using the ultraviolet spectroscopy, scanning electron and laser microscopy. The research shows that modified DDC forms partial water soluble compounds with gold and is selective toward auriferous pyrite and arsenopyrite as compared to xanthate.
