Abstract
The adsorption of ethyl xanthate on pyrite, pyrrhotite, chalcopyrite and sphalerite has been studied using FTIR-ATR techniques and microflotation. Non-activated minerals and minerals activated with copper sulfate have been investigated at different pH values and xanthate concentrations. Diethyl dixanthogen is formed on non-activated pyrite, pyrrhotite and chalcopyrite. Iron xanthate co-exists with diethyl dixanthogen as a monolayer form on pyrite and a copper xanthate surface compound co-exists with diethyl dixanthogen on chalcopyrite. After copper sulfate activation a copper (I) type xanthate compound exists on all of the minerals studied. Acidic pH favours the adsorption of ethyl xanthate on non-activated minerals, whereas the neutral pH range is most favourable for xanthate adsorption on activated minerals.
