Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries. The metal also finds applications in solders and other alloys. Antimony trioxide is the most important of the antimony compounds and is primarily used in flame-retardant formulations.

The main antimony phase of antimonial refractory gold ores is stibnite (Sb 2 S 3). Sodium sulfide is proposed as leaching agent to remove antimony from antimonial refractory gold ores . Meanwhile, sodium hydroxide is also used to prevent the hydrolysis of sodium sulfide. The main equations are expressed as follows:

New Sb isotopic analysis of stibnite ore and LBA metal objects. • The only plausible source for Sb in the first glass making is stibnite. • Sb ores involved in metallurgy are both stibnite and polymetallic ores. • Sb used for glass making may be related to precious metal mining. • Egyptian and Mesopotamian glassmaking were connected to ...

Stibnite (Sb2S3), the principal natural source of Sb in the environment, is linked to the parent weathering material of sinarmonitis (cubic Sb2 O 3 ), stibiconite (Sb 3 O 6 OH), and valentinitis (orthorhombic Sb 2 O 3) ( Hu, Guo, He, & Li, 2016 ). It has been calculated that volcanic activity is responsible for 3%–5% of worldwide Sb emissions ...

A method for isolating Sb (after acid digestion) without introducing artificial mass fractionation was developed, based on the use of a combination of cation exchange chromatography using Dowex AG50-X8 resin and …

Similar variations in δ 123 Sb values of stibnite and mine water suggest that the Sb isotope composition in mine water may be affected by surrounding stibnite ores. However, the difference in Sb isotopic signatures between stibnite and mine waters and the variation in both Sb concentrations and Sb isotopic signature in the mine waters …

Stibnite is named after the latin stibium, which is the old name of the element antimony (Sb). Stibnite was and continues to be the primary ore of antimony. Stibnite forms …

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 ...
