Antimony
Stibnite (Sb2S3) and stibiconite (Sb3+Sb25+O6(OH)) were the only minerals mined in Arkansas for this metal. Stibnite is steel-gray, has a relatively high specific gravity (4.6), a metallic luster, and often forms slender prismatic crystals that may have a curved habit. Stibiconite is an earthy yellow oxide formed by the weathering of stibnite.

Oxidizing Roast; Stibnite the Antimony Mineral
In carrying on a roast, the temperature of the ore is held at first at about 350°C., and the charge is rabbled more or less continuously to prevent or correct caking; later, when part of the Sb2S3 has been converted into Sb2O3 and Sb2O4, the temperature may be raised with advantage. Roasting changes the black sulphide into a yellowish …
