The reverberatory furnace for reduction of antimony oxide was also enlarged: refining at lower temperatures and continuous mechanical casting into ingots gave a high-grade regulus. To enlarge the range of antimony products successful testwork was carried out on a technique characterized by fuel-free, self-oxidation volatilization capable of producing high-quality antimony white from metallic ...

Industrially, reduction of antimony oxide to metallic antimony is achieved by heating and the addition of carbon in a reverberatory furnace. Volatilization of antimony can be reduced by the addition of an alkaline flux but it cannot be eliminated [ 20 ] and volatilized antimony oxide is recovered in flues, condensing pipes, bag houses, precipitators, or a combination [ 21 ].

Fig. 7 shows a type of reduction furnace used by most of the small smelters. This furnace has a cast-iron bottom. Fig. 8 shows a furnace similar to Fig. 7, except that the cast-iron bottom is on wheels, thus facilitating its occasional removal for relining; and that the hot air, from the passage above the roof, can be directed to the inclined grate, producing a partial- gas-firing.
