Antimony in the metallurgical industry: A review of its
Antimony (Sb) is an impurity element that is increasingly encountered in the mineral processing/metallurgical industries of gold, copper and lead. Its occurrence in A new pyrometallurgical process for producing antimony white from antimonial dust was proposed, and it has many advantages such as shorter process, lower cost and good product quality.

Antimony Recovery from End-of-Life Products and Industrial
Ubaldini et al. used alkaline sulfide leaching as a pretreatment step, to remove antimony from a gold-bearing stibnite ore. Antimony was then recovered by A wet chemical process was developed for the separation of gold from gold-bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33% Sb in the form of Processing of Gold Bearing Antimony Ore: Mineral

Perpetua Resources Awarded Department of Defense
Perpetua will receive $200,000 in total to evaluate whether antimony from the Stibnite Gold Project ("Project") can meet military specifications ("Mil-Spec") to help secure America's defense andThe raw material, gold-bearing sludge with arsenic and antimony, was collected from a gold smelter in Xinjiang Province, China. In the smelter, the chlorination roasting method was used to extract precious metals (gold and silver) from the cyanide tailing, which is usually contains gold 5–25 g/t (Ellis and Senanayake, 2004).Selective extraction of arsenic and antimony from gold-bearing sludge

Resilience in the antimony supply chain ScienceDirect
The antimony diversity of supply of both mining and refining is low. • Almost 70% of Sb is mined as by- or co-product. • Companion metals can both have higher and lower resilience. • An additional 25% of Sb production comes from post-consumer recycling. • Stockpiling has played a role in dampening and exacerbating supply disruptions.Antimony has a range of industrial uses in batteries, chemicals, ceramics and glass but by far the most important is in fire retardants. The economically most important ore mineral and principal source for the production of antimony is stibnite. Majority of antimony-bearing ore deposits are associated with the subduction-related western PacificAntimony Critical Metals Handbook Wiley Online Library

MIT’s accidental smelting discovery unlocks the potential of antimony
Electrolysis is also widely used in the production and refining of precious metals, for instance, electrolytic gold is produced using hydrochloric acid as an electrolyte, known as the Wohlwill process, which produces gold at 99.5% purity. Further electro-refining using the Miller chlorination process can improve gold’s purity to 99.999%.Zn leach residues. 1. Introduction. Although most of the gold produced each year originates from primary gold ores or concentrates, a significant amount of gold is recovered as byproduct from the production of base metals (BMs) and from the recycling of scrap. From a gold world production of approximately 2600 metric tons in 2004, about Recovery of Gold as By-Product from the Base-Metals Industries

《重返未来:1999》里的星锑(Regulus) 和 牛顿到底有什么关系
重返未来:1999 星锑 Reverse:1999. * 把自己在微博发的考据搬过来了。. 星锑的姓名很值得说一说，很多解说直接把锑和牛顿联系在一起，我认为这种省略很多关键环节的表达容易让读者误会。. 也看到很多人说"牛顿发现了锑"，"牛顿用Regulus命名了锑"以及"牛 The present research is based on the problem that electrodeposited antimony contains precious gold, the smelting product of antimony–gold ore. By using the basic principle whereby the saturated vapor pressure difference between Sb, Sb 2 S 3,and Au is significant, a two-stage process of sulfuration–volatilization is used to directlyPreparation of Antimony Sulfide and Enrichment of Gold by

Processing of Gold Bearing Antimony Ore: Mineral
A wet chemical process was developed for the separation of gold from gold-bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33% Sb in the form of antimonite. 24% Si in the form of quartz, small quantities of Pb, Fe, Cu, and Ni as well as 63 g/t gold, 60% of it as visible gold.Prepared by Kateryna Klochko [(703) 648–4977, [email protected]] ANTIMONY (Data in metric tons of contained antimony unless otherwise noted) Domestic Production and Use: In 2021, no marketable antimony was mined in the United States.

A selective process for extracting antimony from refractory gold ore
The leaching experiments demonstrated that antimony could be selectively leached from refractory gold ore. Under optimal conditions, the leaching recoveries of antimony, gold, and arsenic were 96.64%, 1.44%, and 0.41%, respectively.
