The mechanochemical reduction of antimony sulphide with elemental iron was studied using a laboratory planetary mill and an industrial eccentric vibratory mill. The composition and properties of the obtained Sb/FeS nanocomposites were analyzed by XRD, VSM, 57Fe-Mössbauer spectroscopy, and SEM methods. The process kinetics shows that most of the reduction (about 90%) is complete after 60 min of milling in the planetary mill. The transformation kinetics is slower when the industrial vibratory mill is used, as it has a lower specific energy input than the planetary laboratory mill. Mechanochemical reduction is a very straightforward, one-step, ambient temperature process that can be readily utilized to make Sb/FeS nanocomposites.
