Antimony is often a high-level indicator of deeper gold deposits, said Barker. Later investigations by Bear Creek Mining included samples topping 1 oz/t gold, as well as antimony-rich samples with gold, silver and arsenic. Hed and Strand, a mine in the Lost River area about 85 miles northwest of Nome, also produced antimony during World War I.
The drinking water plant for local residents is also in the mining area, and health problems are common. “Antimony is an emergent contaminant,” says Faye Liu, a doctoral student at Indiana ...

Based on a long-term antimony price of $8,500 a ton, the company estimates that the net present value of the project is around $279m. Future outlook. Although mining antimony is cheaper in China because of labour costs and the typically large deposits, the trend in declining production is set to endure.
Land within and around the mining area is used for farming. The drinking water plant for local residents was built in the mining area. Zhu says health problems are common at Xikuangshan, possibly the result of antimony intoxication. Zhu says he is discussing a possible collaboration with IU School of Medicine toxicologist Jim Klaunig.

Nov 07, 2020 My topic was Mining Finance in Capital Markets for Antimony Miners. More on that later (because I was the ultimate speaker). The crowd was a select one indeed with key players from the European and Asian regions with a smattering of North Americans and even some parties from Central and South America.
Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.
Jan 17, 2017 Scarce minerals are running out: mining quotas are needed. To ensure that sufficient zinc, molybdenum and antimony are available for our greatgrandchildren’s generation, we need an international mineral resources agreement. Molybdenum is essential for the manufacture of high-grade stainless steels, but at present molybdenum is hardly recycled.

An antimony mine in central Newfoundland has suspended its operations and laid off almost all its employees, saying it's not financially feasible to operate during the continuing COVID-19 pandemic.
Over the last 30 or 40 years, the growing importance of antimony has driven China to improve antimony mining and processing technologies. Many upgrades have been made to the planning and administering of the outdated shaft furnaces and their condensing and dust-collecting systems. The hearth area of reverberatory furnaces for antimony metal ...

When the exposure of antimony orebodies to oxidizing surface environments (air) is accelerated through mining, the weathering of the sulfide-rich ores results in the release of oxidized metals (e.g. iron, copper, lead), metalloids (e.g. arsenic, antimony), and sulfuric acid to the local surface and near-surface waters.
This prompted Chinese antimony producers to cut their sales prices to offload stocks and generate cash to restock on cheaper ore. China imported 5,890 tonnes of antimony ore and concentrates from Tajikistan and Russia in April, accounting for 74.2% of total shipments, according to official but unconfirmed data seen by Fastmarkets.
Antimony Mineral Processing . Process Introduction. Proportion of antimony ore is far greater than proportion of gangue, so it will be separated by using the method gravity separation.This method has many features, high efficiency, energy saving, and environment protection, which can make the low-grade ore enrichment advance.
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) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
According to Mining Indaba, the mine is thought to contain a million ounces and 280,000 tonnes of antimony in SAMREC compliant resources, the company set to implement underground drilling to upgrade resources and complete integrity reviews of the shafts and declines.
Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis. Antimony and some of its alloys expand on cooling.
