Abstract
The article analyzes flotation and adsorption capacity of a new complexing reagent AMD (nitrogen and oxygenated organic compound belonging to phenylpyrazole class) toward sphalerite, chalcopyrite and pyrite, combined with complexing modifiers, at varied consumptions of the reagents, in wide range of alkalinity. The basis for improvement of pyrite and sphalerite separation in flotation is provided.
