A method for the extraction of antimony from stibnite was first described c.1600 by Basilius Valentinus.To obtain high-purity antimony, zone refining is carried out in an atmosphere of inert gas, or antimony is obtained from previously purified antimony trioxide or antimony trichloride.

The main purpose of this study is to characterize and separate antimony from a stibnite concentrate through a low-temperature sulfur-fixing smelting process. This article reports on a study conducted on the optimization of process parameters, such as flux and zinc oxide weight percentage, in charging, smelting temperature, smelting duration on the antimony yield, resultant crude antimony grade

Production process. The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 C, the temperature at which stibnite melts and separates from the gangue minerals.

Antimony. A native element, antimony metal is extracted primarily from stibnite, which contains 72 percent antimony and 28 percent sulfur. Stibnite is mined in only a few countries, with China being its largest producer. Antimony is used for many technological and industrial purposes. Antimony is used as a hardening alloy for lead, especially

Industrial Uses: Stibnite is mined and smelted to obtain antimony, an important metal. Smelting is a process where a metal is obtained by heating metal-rich rocks beyond the melting point (8). Antimony is a very useful mineral because it expands when it cools and freezes.

Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.

Many minerals contain antimony; however, stibnite and antimonial lead ores are the main sources of the metal. Stibnite (Sb2S3) and its alteration oxide, stibiconite (Sb 3+ Sb 2 5+ O 6 (OH)), were the only minerals mined in Arkansas for this metal. Stibnite is steel-gray, has a relatively high specific gravity (4.6), and has a metallic luster.
