Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. Valentine of Germany.
Antimony (Sb) is naturally present in the earth's crust at levels of about 0.2–0.3 mg/kg (ppm), but these levels vary by location (Telford et al. 2008). It can be transported into streams and waterways from natural …

Techniques for the processing of antimony-bearing ores encompass a wide range of techniques from traditional hand sorting, which is dependent on plentiful and cheap labour, to technologically advanced, capital-intensive mineral processing. The main antimony products in international trade are stibnite and subordinate stibnite-berthierite …
The mineral processing of antimony. Originally antimony was mined and hand sorted to effect concentration. Since the bulk of primary production is in China, where labor is plentiful and cheap, surprisingly, hand sorting still finds a large application. However, in recent years, many other unit operations are used in the mineral …
These observations have led the European Commission to highlight antimony as a critical raw material in 2014, with an expected supply–demand gap …
Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol.The most …
Antimony and antimony metal compounds are very suitable materials for semiconductor and thermoelectric devices [13, 14]. Antimony is also widely used in military, rubber, and other industries. The reductive smelting process for antimony metal has garnered significant attention from researchers in recent years.
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of …
Antimony (Sb) is the 51st element on the periodic table. Together with N, P, As, and Bi, Sb locates in group 15 on the table. Sb exists in nature mainly as sulfide mineral stibnite (Sb2S3). ...

Antimony resides on the table of elements identified by atomic number 51 and symbol Sb (stibium) alongside lead (Pb), tin (Sn) and bismuth (Bi). It is mainly sourced in China in its sulfide mineral stibnite form. As a metalloid, it has a combination of metal and non-metal properties, which makes it a very versatile element.… Read More »Antimony
Metallic antimony with a purity of 99.4% is obtained when the antimony oxide is reduced in a reverberatory furnace at 1200°C by reducing coal. During the refining process in a reverberatory furnace, any As accompanying the antimony oxide is removed by the addition of sodium hydroxide. AAR is generated during the As removal process.
