Extraction of Antimony

The production of "secondary antimony" (i.e. the recovery of antimony from alloys and residues) forms an important means of obtaining the metal. In the United States of America in 1928, between 170,000 and 180,000 tons of old lead accumulators containing 3 per cent, antimony were available.

Except for the ore which came from Bolivia, we worked with commercial products coming from a local chemical dealer."

Antimony Mineral, Extraction of Antimony, Antimony Mineral

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. After gravity separation, the antimony will be purified by floatation.

Extraction Of Antimony Resi Suzhou ECeurope Market

Antimony is a kind of heavy metal elements, have chronic toxicity and potential carcinogenicity, is a global environmental pollution. Natural concentration of antimony in water less than 1 mu g/L, but the water content of antimony in mining area is up to hundreds or thousands of u g/L. Water environment, mainly trivalent antimony (Sb) (Ⅲ) and five price (Sb (V)) two kinds of price of uranium

Extraction of antimony by a copper chloride extractant

Jun 01, 2004 Antimony extraction is more effective in chloride concentration range of 1.2 to 2.5 M. To reduce this extraction, the chloride concentration in the aqueous solution should be adjusted to below 1.2 M or higher than 2.5 M. To minimize the antimony extraction, the acidity of the aqueous solution should be kept as low as possible.

ATSDR Public Health Statement: Antimony

Jan 21, 2015 Antimony is a silvery white metal of medium hardness that breaks easily. Small amounts of antimony are found in the earth's crust. Antimony ores are mined and then either changed into antimony metal or combined with oxygen to form antimony oxide.

Antimony Element information, properties and uses

Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol.The most famous user was the temptress Jezebel whose exploits are
