An analytical review of the main gold-antimony ores in the Russian Federation is presented. The practice is shown and the results of the concentration of Au-Sb ores in the Sarylakh, Sentachan, and Maltan deposits (the Sakha Republic (Yakutia)) are presented. A series of selective reagents for the flotation of antimonite from complex gold …
economic recovery of mercury metal and the concurrent recovery of antimony as metal or salts. If standard mercury-recovery techniques are applied to such ores, the antimony content interferes with the effective production of mercury metal; further-more, the antimony is lost.

The word antimony comes from the Greek phrase anti plus monos —"a metal seldom found alone." Although the name was intended to describe the metal's mineralogical association in ores, it also aptly …
of antimony- and bismuth- bearing ores is as yet at an early stage (Batyrbekova, 1973); in the studies reported here, the prospects of bacterial leaching these ores are examined, ... (1979) have used a SRB culture as sulfidizator in the concentrating of oxidised antimony and bismuth ores, where it acts as a desorbent depressor during the ...
The flow chart that was developed for recovering antimony while concentrating the gold-bearing ore ... "Environmental problems and the latest trends in the efficient use of gold-antimony ores and concentrates," in: Efficient Use and Regeneration of Natural Resources [in Russian], VINITI, Moscow (2006), pp. 37–41.
Antimony is a metalloid element having common oxidation states of 5+ and 3+. It is a lustrous silvery-white solid, which is quite brittle and exhibits a flaky texture. Antimony is classified as a critical/strategic metal. Stibnite, jamesonite, and antimony-gold ores are the most common sources of antimony.

reasonable and efficient use of antimony oxide ores. Since antimony occurs mainly in elemental form or as stibnite, senarmontite, valentinite or antimony ochre (cervantite and stibiconite) in the Earth's crust, anti-mony sulfide is the main component of global anti-mony mineral resources; thus, it has a high commer-cial value [16].
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. …
Abstract. Technologies for remediation of industrial effluents and natural sources contaminated with antimony - a pollutant of emerging concern - are just …
Imports of Antimony Ores and Concentrates Imports into Thailand. Antimony ore and concentrate imports into Thailand dropped markedly to X tons in 2022, reducing by X% on the year before. In general, imports showed a abrupt decline. The most prominent rate of growth was recorded in 2021 with an increase of X% against the …
The types of ores used for processing are: mono-antimony sulfide ore, sulfide-oxidized mixed antimony ore, tungsten antimony gold polymetallic sulfide …
The article presents results of hydrometallurgical and bio-treatment of antimony ores and recommend new dissolvents for antimony sulfides. The authors introduce a processing plant which is a ...
The technology of concentration of the sulfide antimony-arsenic gold-bearing ore containing 3.6 g/tn Au, 0.3% Sb, and 0.4% As is developed. This technology implies the flotation separation of antimonite and arsenopyrite into separate products and allows them to perform in various cycles, increasing production efficiency due to a …
