Sep 27, 2016· Contains about 71% antimony, and sometimes carries gold and silver. Crystals are often long and slender; cleavage, very perfect, often showing in streaks, with duller spots or bands between. This is the common ore of antimony, a metal used in making Babbitt metal, type metal, and other alloys.
Antimony is a native element that can occur in a natural state, but it is rarely pure. It almost always contains some arsenic, and may also contain traces of silver, iron, and sulfur. On a fresh or preserved surface, Antimony has a tin-white color with a slight blue tinge. Otherwise, it is dark gray due to tarnish.
Food contains small amounts of antimony: the average concentration of antimony in meats, vegetables, and seafood is 0.2 to 1.1 parts per billion (ppb). (1) People who work in industries that process antimony ore and metal, or make antimony oxide, may be exposed to antimony by breathing dust or by skin contact. (1) Assessing Personal Exposure
Of the antimony ores proper, the major mineral is antimonite (Sb2 S 3), which contains up to 71.4 percent Sb; in rare cases, antimony ores are represented by complex sulfides of antimony, copper, mercury, lead, and iron (berthierite, jamesonite, tetrahedrite, livingstonite), as well as by oxides and oxychlorides (senarmon-tite, nadorite) of antimony.

Antimony is a minor ore of the element antimony, although most antimony comes from antimony compounds (namely Stibnite), which are much greater in abundance. Antimony has a very interesting property: It is similar to water, in that instead of contracting
recognized. Natural antimony consists of a mixture of two stable isotopes that have atomic weights 121 (57.25 percent by weight) and 123 (42.75 percent by weight); in addition, about three dozen radioactive isotopes are known. Antimony’s average concentration in the Earth’s crust is 0.20 gram per metric ton (g/t). Antimony metal melts at
Phase Composition The XRD patterns of the tailings were shown in Fig. 2. The results show that the antimony ore tailings mainly include stibnite, antimony sulfide, and quartz. Other minerals may not be detected because of the low content. Heavy Metals in Tailings The situation of heavy metal in tailings samples are given in Table 1.
The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased. Antimony Ore any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible. Of the antimony ores proper, the major mineral is antimonite (Sb2S3
the average temperature of the Xikuangshan Mine is 16.70ºC. Many gullies have been developed in the area, and the two main rivers are the Xuanshan and Qingfeng seasonal rivers belonging to the Zijiang River system. The antimony deposit is a layered breccia-type metal deposit in a structural fracture belt. The main mineral is stibnite.

Jan 29, 2017· In order to study the properties of the tellurium-antimony alloys, sufficient of each metal was taken to form a button weighing about 20 grammes. In all, fifteen alloys were made, varying from 5 to 95 per cent, of tellurium. The antimony used was the so-called chemically pure metal, which was found to contain traces of lead and sulphur.
Mar 18, 2016· Hence the percentage of extraction is 73.5 per cent.; i.e., the loss amounts to 7 per cent., taking the trioxide as containing 80.5 per cent. Sb. Summing up, we have a loss of about 19 per cent, of antimony from ore to regulus. The consumption of coal is 0.55 ton per ton of regulus, and the average life of the hearth bottom is 12 weeks.

Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in the United States that produce antimony
Jun 01, 2019· Ye et al. (2015) proposed a low-temperature molten salt smelting process that could directly produce antimony from its ore. Zinc oxide (ZnO) was added as a desulfurization agent, and sulfur was fixed in the form of ZnS. Under the optimum conditions, the average direct recovery rate of antimony reached 92.88%.
Composition of type metal. Type metal is an alloy of lead, tin and antimony in different proportions depending on the application, be it individual character mechanical casting for hand setting, mechanical line casting or individual character mechanical typesetting and stereo plate casting.

Antimony, which in July, 1914, had been down to a monthly average price of 7.11 cents for Cooksons, and from 5.44 upward for other brands, rose gradu ally, though unsteadily, to the end of 1915, when Chinese, .Japanese, and American antimony were quoted at about 40 cents a pound.
Antimonite (a.k.a. stibnite) (Sb 2 S 3 ), the predominant ore mineral of antimony, was known as early as 4000 BC (Anderson, 2012) and has been used in ancient Egypt as eyepaint (kohl) and glass
The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 metric tons per year.
