Abstract
In the production of antimony oxide from antimony concentrate, 20-40 per cent of " fusible " waste oxide obtained in the operation of the process is added to the concentrate before or during oxidation, whereby a purer product is obtained. Oxidation is effected with free access of air, or with oxygen.
