The ore bodies mainly occur in lamellar, quasi-lamellar and lenticular forms in the altered rocks, and are strictly controlled by anticline structure. In terms of space, elemental paragenesis-separation takes place between gold and antimony deposits, i.e. the gold deposit has antimony ore spots, and the antimony deposit has gold ore spots.

1. Introduction. Antimony (Sb) is a metalloid widely used in various industrial fields, such as in the production of flame retardants, batteries, plastics, and catalysts [].With rapidly increasing use, Sb is currently the ninth most mined metal in the world [].Due to natural processes and human activities such as mining and smelting, coal combustion, …

In recent years, with the increasing demand for antimony resources, the mining activities of antimony ore are also increasing year by year. The large-scale mining and smelting activities of …
Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …
Celep et al., 2011a, Celep et al., 2011b and Alp et al. (2014) increased silver and gold extraction, in a subsequent cyanidation from a refractory antimony ore, using an alkaline pretreatment with Na 2 S and NaOH (2011a), NaOH (2011b) and KOH (2014), achieving up to 94% silver extraction and 87% of the gold with 86% antimony removal …
main ore-controlling structures are strike-slip and high-angle reverse faults. Common characteristics include: the paragenesis of high purity gold (940-1,000 fineness) with ... correlation of gold with antimony occurs in the richest vein deposits. Gold of high fineness in alluvium around such deposits is an effective prospecting guide.
Antimony occurs in a number of different deposits such as Sb-bearing minerals (boulangerite, a lead-rich mineral), bournonite, gudmundite (an iron-rich mineral), and polybasite, which have also been recognized as minor antimony sources . Antimony ore is frequently associated with undesirable elements, such as Hg .
Zhaxikang antimony polymetallic ore deposit, the first super large deposit discovered in northern Himalayan metallogenic belt (NHMB) and first SEDEX discovered modified by hot spring type Mn-Fe-Sb ...
In this work, we investigated in situ isotopic compositions of antimony (Sb) minerals from two substages of the ore deposits near Pezinok (Slovakia). The δ123Sb values of the primary Sb minerals range from −0.4 and +0.8‰ and increase progressively along the precipitation sequence. In the substage II, the early-formed gudmundite …
Moreover, China's antimony ore mining accounted for 52% of the world's antimony mining in 2020, with extraction of antimony ores also ranking first in the world . With the increasing development of …
In value terms, antimony ore and concentrate production surged to $2.3B in 2021 estimated in export prices. Overall, production saw a pronounced curtailment. The …
• Financial models are based on annual mining and processing of 250,000 tonnes of ore with the aim of producing over 200,000 oz saleable gold and nearly 5,000 tonnes saleable antimony over a 5 ...
Stibnite is also the mineral name for antimony ore. Mining for gold and antimony began at Stibnite in 1931. Later a body of rich tungsten ore was found. During World War 11, Stibnite produced ninety-eight percent of America's antimony, and much of her tungsten. Both metals were vital for making machines and weapons for fighting the war.
Antimony Ore. any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible. Of the antimony ores proper, the major mineral is antimonite (Sb2 S 3 ), which contains up to 71.4 percent Sb; in rare cases, antimony ores are represented by complex sulfides of ...
Estimates of the abundance of antimony in the Earth's crust range from 0.2 to 0.5 parts per million. Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) …

Introduction: The Abunabu antimony mining area is located between the Indus–Yarlung Tsangpo suture and the southern Tibetan detachment system. Ore deposits in the mining area provide an excellent opportunity to understand the nature and genesis of antimony mineralisation in the Tethys Himalayan metallogenic belt.Methods: In this …
At Shuiyindong, gold-bearing arsenian pyrite precipitated from H 2 S-rich fluids by sulfidation of the ore host, and/or mixing with Fe-rich fluids produced by ferroan mineral dissolution in the alteration zones nearby (Su et al., 2009b, 2018). Therefore, Au-rich and Sb-rich fluids were probably formed via fluid homogenization by chemical re ...
NASA's Hubble Telescope has obtained images of an asteroid so rich in metals that its worth puts our global economy to shame. Think $10,000 quadrillion ($10,000,000,000,000,000,000), compared to ...

A significant antimony resource is located at Costerfield. In addition, there has been important historical production from the Ringwood and Coimadai deposits. Stibnite is also a minor constituent of gold-bearing sulphide reefs of the Bendigo Zone and there is bournonite (PbCuSbS 3) in the silver–lead ores of eastern Victoria.
