Antimony. A native element, antimony metal is extracted primarily from stibnite, which contains 72 percent antimony and 28 percent sulfur. Stibnite is mined in only a few countries, with China being its largest producer. Considerable research efforts have been devoted in recent years to cover mineralogical and mineral processing aspects of antimony ores, with a greater emphasis on hydro- and pyrometallurgical processing of antimony concentrates (Anderson, 2019, Grund et al., 2011, Rohner and Millard, 2016, Schwarz-Schampera, 2014; Solozhenkin and Stibnite froth flotation: A critical review ScienceDirect

Availability, Toxicology and Medical Significance of Antimony
Antimony has been known and used since ancient times, but its applications have increased significantly during the last two centuries. Aside from its few medical applications, it also has industrial applications, acting as a flame retardant and a catalyst. Geologically, native antimony is rare, and it is mostly found in sulfide ores.To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium A selective process for extracting antimony from refractory

Antimony Metallurgy SpringerLink
Antimony Metallurgy. 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. 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 Antimony Critical Metals Handbook Wiley Online Library

This study aimed to introduce a vacuum process for recovering and enriching antimony from low-grade stibnite. At the pressure of 10 Pa, by controlling heating temperature, Sb 2 S 3 and Sb 2 O 3 from stibnite (12.8 wt% Sb) was evaporated and enriched.

Development of a Two-Stage Hydrometallurgical Process for Gold–Antimony
Therefore, processing these complex ores typically involves a sequential approach, starting with the removal of antimony materials followed by the gold extraction [7,8]. However, gold–antimony ores often exhibit a refractory behavior due to the association of gold with sulfides, such as antimonite (Sb 2 S 3), pyrite (FeS 2), and arsenopyriteAntimony has been produced from ores in over 15 countries. As shown in Table 2 (Carlin, 2012), world reserves of antimony are estimated to about 1.8 million metric tonnes.As China, the leading producer, accounts for about 90% of the world's mined production and the vast majority of the reserve base (i.e. reserves consist of The metallurgy of antimony ScienceDirect

Mineral Resource of the Month: Antimony EARTH Magazine
Antimony is the 63rd-most abundant element in Earth’s crust. It is less abundant than tin, arsenic and the rare earths, but more so than bismuth, mercury and silver. Antimony tends to concentrate in sulfide ores along with copper, lead and silver. It occurs sparingly as a free element, but when it does it is usually in association withIt can be seen from Eq. () that Sb 2 S 3 is deposited on the surface of gold particles, forming a dense product layer and hindering the diffusion of CN − and O 2 to the gold particles, leading to low leaching ratio [3, 4].Effect of Antimony on Pretreatment Process.

A review of the technologies for antimony recovery from refractory ores
Many countries will have to rely on recovering antimony from refractory ores and metallurgical residues. For the purpose of efficient and selective antimony recovery with minimal economic cost and environmental impact, researchers proposed various innovative pyrometallurgical, hydrometallurgical, and electrochemical processes.Antimony is primarily obtained from mining ores (rocks and sediment containing antimony together with minerals or metals). Most of the world’s antimony comes from China, and European companies require an alternative solution. Thomas and his team are developing a pilot plant to process antimony from various sources in large Non-toxic, no-waste process technology for antimony recovery

How to Remove Arsenic, Antimony & Bismuth from Copper
The ores of copper are usually associated with minerals containing arsenic, antimony and bismuth.Whatever the means adopted for extracting the copper, these metals are usually found, to a greater or less extent, in the product. There is, however, usually some elimination in the various metallurgical operations to which the ores are subjected, and improve mineral processing of antimony to ensure reasonable and efficient use of antimony oxide ores.
