Zone refining of antimony trisulfide
Abstract. Antimony trisulfide with melting point as high as 566°C was prepared by zone refining in sealed quartz ampoules. The deviations from the stoichiometry in the vicinity of Sb 2 S 3 composition were checked by DTA measurements. Some electrical and optical properties of zone refined, high resistivity material were determined.

Three-phase fluidized bed leaching of antimony refining slag
Flow curves of antimony refining slag. 1020 -y (5_1) apparent viscosities of the slag pulp of the - 0.9 + 0.4 mm, - 0.4 + 0.097 mm and -0.097 mm particles were measured and flow curves were plotted. From the shape of the plots (Fig. 2), it was judged that antimony refining slag pulp is a power-law fluid.
