Abstract
Potassium butyl xanthate adsorption at galena and chalcopyrite is characterized using the methods of atomic force microscopy and spectroscopy. It is found that layers generated on galena and chalcopyrite surface as a result of agitation in distilled water and interaction with potassium butyl xanthate solution have cardinally different morphology. Observations over adsorption of the reagent in liquid phase reveal different mechanisms of the reagent coating growth on these minerals.
