Abstract: The effect of mechanical activation on the surface properties of zinc, lead (II) and antimony (III) sulphides produced by dry intensive grinding in a vibration mill and a planetary mill was studied by ESCA and IR methods. It was found that favourable conditions for mechanochemical transformations including formation of variable surface species were created by grinding.

Keywords: galena; mechanical activation; sphalerite; stibnite; surface oxidation; dry grinding; dry machining; surface properties; zinc sulphide; lead sulphide; antimony sulphide.
