Hence the percentage loss in antimony is: 100 x (0.25 x 4480) – (1224 x 0.805)/ (0.25 x 4480) = about 12 per cent. Each furnace requires two workmen per shift of 12 hours. (b) Reduction of the Trioxide to Regulus.—The reduction furnace can smelt two charges per 24 hr. of the following composition:

The elimination of arsenic and antimony in this operation is considerably greater than that of bismuth. In the case of slags produced from blast-furnace practice, smelting similar materials, I have never found more than 0.015 per cent, of arsenic, and only traces of antimony.

An FeO-SiO2-CaO-Na2O quaternary slag with low melting point was developed for the bath-smelting reduction of Sb2O3. First, the optimum composition of the designed slag was determined through practical experiments to be 36.2% FeO, 31.9% SiO2, 12.0% CaO, and 20.0% Na2O, such that FeO/SiO2 was 1.14.

The blast furnace is generally used for mixed sulfide and oxide ores, and for oxidized ores containing up to about 40% antimony; direct reduction is used for rich oxide ores. Some antimony ores are treated by leaching and electrowinning to recover the antimony. The concentrates may be leached directly or converted into a complex matte first.

Carbothermic reduction of a commercial smelter dust resulted in the recovery of 95 pct of copper, over 80 pct of arsenic and antimony, and over 50 pct of bismuth and tin in the combined metallic copper and matte production. Copper recovery improved as the weight ratio of FeO to SiO2 in the slag approached 1.7.

Usually, multiple oxidation and reduction processes are required to separate lead and antimony, resulting in a low recovery rate of lead and antimony and many return materials for repeated smelting.
