In the northwestern margin of the Youjiang basin (NWYB) in SW China, many Carlin-like gold deposits are highly antimony (Sb)-rich, and many vein-type Sb deposits contain much Au. These deposits have similar ages, host rocks, ore-forming temperatures, ore-related alterations and ore mineral assemblages, but the Au and Sb metallogenic relations and …

Abstract The article discusses the features of the composition, age, and genesis of gold–antimony mineralization of the East Sayan based on the example of the largest Tumannoe ore occurrence. It is shown that objects of this type are rare in the considered region. In the course of studies, it was found that stibnite, pyrite, and …

Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations were low …

However, it is often the primary focus of extraction in gold–antimony vein mining operations. The inclusion of antimony in gold ore poses challenges in terms of processing, leading to increased difficulty and cost. Consequently, it may be necessary to accumulate a quantity of gold ore with a significant antimony content [3,9].

Member of: Arsenic Group. Name: From the medieval latin 'antimonium', originally applied to stibnite. The etymology is uncertain; the popular etymology, from ἀντίμοναχός anti-monachos or French antimoine, still has adherents; this would mean "monk-killer", and is explained by many early alchemists being monks, and antimony being ...

An ore vein is a rare underground terrain feature that provides massive amounts of ore. Ore veins occur as large branching networks of rock with high concentrations of associated ore. Copper veins are largely made of granite associated with copper ore and raw copper. Iron veins are tuff associated with iron ore and raw iron. Ore veins can snake and branch …
