ABSTRACT:
A process is provided for the production of antimony oxide from antimony sulfide which comprises the steps of comminuting the antimony sulfide to form a plurality of antimony sulfide containing particles, mixing the antimony sulfide containing particles with substantially pure oxygen, reacting the antimony sulfide with oxygen to form a gaseous stream of antimony oxide and sulfur dioxide, cooling the gaseous stream below the boiling point of antimony oxide, separating the condensed antimony oxide from the sulfur dioxide, further cooling the separated sulfur dioxide and utilizing the cooled sulfur dioxide to cool the gaseous stream of antimony oxide and sulfur dioxide. Apparatus for accomplishing this process is also provided.
