84 THE METALLURGY OF ANTIMONY 3. Preparation of the Volatile Trioxide.—The so-called volatilising roasting is for the production of the volatile trioxide when the admis- FIG. 19.—Plau. Scale=-^j. sion of air is restricted and higher temperatures are maintained. Steam at a high temperature can effect the formation of the trioxide, with the simultaneous evolution of hydrogen sulphide. n ft FIG. 20.—Section on C D. Scale = The advantages of this method for treating antimony ore are:— (1) The separation of arsenic from antimony, due to the fact that arsenic oxide is more volatile than antimony trioxide.
THE METALLURGY OF ANTIMONY. 85 (2) If the ore contains gold or silver, the latter is generally found in the residues after volatilisation. (3) This method makes it possible to treat low-grade ores, e.g. 7 per cent, to 20 per cent., with profit. FIG. 21.—Section A B. Scale= (4) With different devices for condensation, the loss of antimony is practically nil. (5) The economising of fuel. (6) The trioxide, thus condensed, can be reduced to metallic antimony, or it can be used for other industrial purposes—for instance, to make paints. n_ FIG. 22.—Perspective. Scale=5^- From these we might be led to believe that this method forms the proper line of development of the metallurgy of antimony in the future, judging from the most favourable results that have already been attained in France, in which country this method has reached its highest perfection. r
