Federal Register Final List of Critical Minerals 2018
Using that methodology, and several other sources of data, the USGS applied two principal criteria to evaluate minerals for inclusion on the draft list of critical minerals The Hirfindal-Hirschmann index, which measures country concentration of production, and the USGS net import reliance metric based on USGS's annual Mineral Commodities
The ore called stibnite is the predominant ore from which antimony is produced and where it chemical symbol Sb originated. It has been estimated that about 80 or 90% of worldwide antimony production comes from China and that established global reserves of this metal
Primary antimony metal and oxide were produced by one company in Montana using imported feedstock. Secondary antimony production was derived mostly from antimonial lead recovered from spent lead-acid batteries. The estimated value of secondary antimony produced in 2018, based on the average New York dealer price for antimony, was about $34 million.

Antimony (Sb) is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification. The metal's main use is to impart stiffness and hardness to lead alloys.
antimony is one of a few elements that expand as they freeze. Antimony is a poor conductor of electricity and heat, and can be toxic in some cases, but less so in solid form. More than 100 mineral species of antimony are known; however, it most commonly combines with sulfur to form antimony sulfide or "stibnite" (Sb 2S 3).
This worked. The price of antimony soared to a peak of around USD17,000 per tonne in 2011 and was around USD9,570 in 2014. Supply and Demand. The United States Geological Survey ("USGS") estimates that world mine production of antimony metal in 2014 was 160,000 tonnes.

Critical mineral resources of the United States USGS
Mineral commodities are vital for economic growth, improving the quality of life, providing for national defense, and the overall functioning of modern society. Minerals are being used in larger quantities than ever before and in an increasingly diverse range of applications. With the increasing demand for a considerably more diverse suite of mineral commodities has come renewed recognition
Most of today's antimony is mined in China, though production is scaling back in an effort to clean up their environment. Antimony is rated as a top-20 element required for maintaining current lifestyles. Global supply is estimated to be "depleted" in thirteen years, according to the USGS. Maine has several antimony deposits.
Chapter 29 Antimony deposits of Myanmar Geological
Antimony is a 'critical metal' in short supply in the world markets (Gunn 2014). Mining of antimony ores in Myanmar reached 9000 metric tons in 2014 (USGS 2015), establishing Myanmar as a significant global source of antimony ore, the bulk of which is exported to China. The majority of the antimony ore in Myanmar is in syntectonic quartzstibnite veins and breccias (Type I of Dill 1998

Bismuth is a brittle, silvery-green metal that has a low melting temperature and high specific gravity. Being both stable and non-toxic, bismuth is often used as a replacement for toxic metals such as antimony, cadmium, lead, and mercury.

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.

Antimony standard may be used in the quantitative determination of antimony in geological samples using inductively coupled mass spectrometry and flow injection hydride generation atomic absorption spectrophotometry. Analysis Note 1000 mg/L Sb in 2% nitric acid (contains HF traces), prepared with high purity Sb metal, HNO 3, HF and water
The metal antimony was known to German chemist Andreas Libavius in 1615 who obtained it by adding iron to a molten mixture of antimony sulfide, salt and potassium tartrate. This procedure produced antimony with a crystalline or starred surface. ^ "U.S. Geological Survey, Mineral Commodity Summaries Antimony" (). 1 January 2016.
Analysis of Antimony by Hydride-generation Atomic Absorption Spectrometry (USGS and XRAL laboratories) Method. 250-mg sample aliquots are weighed into Teflon vessels. A mixture of nitric and hydrochloric acids is added, and the mixture is left to stand for 3 hours. Hydrofluoric and perchloric acid is added, and the sample is heated overnight.

According to the US Geological Survey (USGS), the USA produced no marketable antimony in 2014, and there is not much antimony in Europe either. It ranks third on the British Geological Survey Risk List and is on the EU's list of critical materials. Better get digging. Unsurprisingly, China mines the majority of the world's antimony.
Base metal occurrences are known throughout the State and prospectivity under alluvial cover in the State's northwest is particularly strong. Much of the recent exploration for base metals has been driven by a growing understanding of geological links between parts of Victoria and metal provinces in both Tasmania and New South Wales.
The deposit was the third largest antimony producer in Mexico. Donald E. White (U. S. Geological Survey Bulletin 960-B, Antimony Deposits of Soyatal District, State of Queretaro, Mexico, 1948) said that the production (p. 40) was estimated through 1943 at 25,630 metric tons of metal contained. USAC is sourcing oxide mill feed and direct
antimony produced by the US Geological Survey (USGS) is difficult because the USGS does not provide chemical-specific breakdowns for antimony compounds. The greatest use of antimony, as a flame retardant, accounted for 9,930 metric tons of antimony, primarily as antimony oxide. Of the 4,110 metric tons of nonmetal antimony consumed
