Antimony

The British Geological Survey (BGS) reported that in 2005 China was the top producer of antimony with approximately 84% of the world share, followed at a distance by South Africa, Bolivia and Tajikistan. Xikuangshan Mine in Hunan province has the largest deposits in China with an estimated deposit of 2.1 million metric tons. In 2016, according to the US Geological Survey, China accounted for 76.9% of total antimony productio

US3944653A Process for preparing high purity antimony

Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.

Antimony Trioxide Applications and Specifications

Direct process In this process, crude antimony oxide is roasted in the presence of air to give ATO vapors. The vapors are then condensed to convert the vapor to white powder. These powders are further filtered to give antimony trioxide powder.

Antimony Compounds United States Environmental

Antimony ores are mined and then either changed to antimony metal or combined with oxygen to form antimony oxide. (1) Antimony trioxide is a white powder that is very slightly soluble in water. (1) Antimony metal is a very brittle, moderately hard metal. (1) The chemical symbol for antimony is Sb, and it has an atomic weight of 121.75 g/mol. (1)

Antimony Recovery from End-of-Life Products and Industrial

Feb 08, 2016 Antimony is produced from stibnite ore (Sb 2 O 3) which is processed into antimony metal and antimony oxide (Sb 2 O 3).

Antimony Mining Encyclopedia of Arkansas

Many minerals contain antimony; however, stibnite and antimonial lead ores are the main sources of the metal. Stibnite (Sb2S3) and its alteration oxide, stibiconite (Sb 3+ Sb 2 5+ O 6 (OH)), were the only minerals mined in Arkansas for this metal. Stibnite is steel-gray, has a relatively high specific gravity (4.6), and has a metallic luster.

Stibnite often precede lead salts as activators also useful copper salt or a combination of lead salts copper salt, then collector flotation.

Antimony trioxide

Global production of antimony(III) oxide in 2012 was 130,000 tonnes, an increase from 112,600 tonnes in 2002. China produces the largest share followed by US/Mexico, Europe, Japan and South Africa and other countries (2%). As of 2010, antimony(III) oxide was produced at four sites in EU27. It is produced via two routes, re-volatilizing of crude antimony(III) oxide and by oxidation of antimony metal. Oxidation of antimony meta

ANTIMONY OXIDE LISTING BACKGROUND US EPA

The U.S. relies heavily on imports of antimony metal and ore in the production of antimony oxide. This is because domestic ore has high levels of arsenic, making use of this ore unattractive. In 1988, a total of 33,106 tons of ore was imported into the U.S., with China being the largest supplier. Some other

Antimony Ore Article about Antimony Ore by The Free

Antimony ores are formed through the filling of rock fissures by low-temperature hydrothermal solutions, as well as through the replacement of the solutions by antimony minerals. There are two types of antimony deposits of industrial significance.

Extraction of Antimony

For the treatment of lead-antimony alloys the Harris process is largely employed in England and some other countries. In this process the scrap metal is melted with an oxidising alkaline flux. Arsenic, antimony and tin are then removed by skimming as sodium arsenate, antimonate and stannate.

Extracting antimony from high arsenic and gold-containing

Jun 01, 2019 The sulfide antimony ore is first volatilized and oxidized into antimony trioxide (Sb 2 O 3) in a blast furnace, and then Sb2 O 3 is reduced to antimony metal in a reverberatory furnace (Hua et al., 2003; Qin et al., 2015).

Definition of Antimony MedicineNet

Mar 29, 2021 Antimony occurs naturally in the earth. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Antimony breaks easily, but when mixed into alloys, it is used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, and pewter.

General Discussion on Smelting.—Practically all of the shaft furnaces mentioned for the volatilization process are of the same type, except with minor differences in details as to the form of the grate- bottom and as to size. The ideal ore for treatment in such furnaces is one containing antimony from 15 to 25 per cent.; ore above 40 per cent.

Oct 01, 2020 Shaking table separation, the main method in dealing with antimony oxide tailings, has too many defects such as poor operational stability and low recovery. A new technical idea was proposed to solve these problems by using an agitated Reflux Classifier to pre-concentrate the tailings before they went to shaking tables.
