extraction antimony ore
20 Interesting Facts About Antimony
He described the extraction of metallic antimony from its sulfide ore in his treatise "The Triumphal Chariot of Antimony," published sometime between A.D. 1350 and 1600. When Gutenberg and others began using cast metal printing type in the mid-15th century, antimony was incorporated.

Hence the percentage of extraction is 73.5 per cent.; i.e., the loss amounts to 7 per cent., taking the xide as containing 80.5 per cent. Sb. Summing up, we have a loss of about 19 per cent, of antimony from ore to regulus. The consumption of coal is 0.55 ton per ton of regulus, and the average life of the hearth bottom is 12 weeks.
