A Review on Pyrometallurgical Extraction of Antimony from
Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology While an extensive analytical project on 360 metal objects, ores sources, and metallurgical debris has been on-going since the 1980s, Major Anatolian centers of Old Assyrian trade such as Kültepe and Acemhöyük do not yield antimony-bearing metals (>1% antimony) [e.g., 57; 124; 125].

The EU is a net importer of Antimony ores and concentrates in the observed period (2000-2021). Like all otherElectrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold.

Abstract. Of the 60 metals and semimetals that are known today, only 9 were known from antiquity to the Roman period, namely copper, gold, silver, lead, tin, iron antimony, mercury and zinc. The semimetal arsenic, which occurs regularly in ancient artefacts from the beginning of extractive metallurgy, was unknown, as was nickel.The remaining 10% comes from other countries [21], shown in Figure 2, and given in Table 5. rocesses 2022, 10, x FOR PEER REVIEW 5 of 38 produce ~3000 tonnes/year of antimony in the late '70sMain producers of antimony in the world.

Antimony ores are mined and then either changed to antimony metal or combined with oxygen to form antimony oxide. (1) Antimony trioxide is a white powder that is very slightly soluble in water. (1) Antimony metal is a very brittle, moderately hard metal. (1) The chemical symbol for antimony is Sb, and it has an atomic weight of 121.75 g/mol. (1)The concentrated ore must be converted into a form which is suitable for reduction. Usually the sulphide ore is converted to oxide before reduction. Oxides are easier to reduce. Thus isolation of metals from concentrated ore involves two major steps viz., (a) conversion to oxide, and (b) reduction of the oxide to metal.inorganic chemistry Why are the sulfide ores generally

Antimony (Sb) is a naturally occurring metalloid element. It can exist in a variety of oxidation states (−III, 0, III, V), but is mainly found in two oxidation states (III and V) in environmental, biological and geochemical samples [].The abundance of Sb in the Earth’s crust is in the order of 0.2–0.3 mg kg −1 [].The concentration of Sb in soils is higher than Ores contain, in all cases, a much higher concentration of the metal than the average concentration of that metal in the earth’s crust. Geochemists have estimated the crustal abundance of the elements by: (1) calculating, from chemical analyses in the literature, the average composition of each of the major types of rock in the crust and (2) multiplying From Ores to Metals SpringerLink
