History: Antimony Metal - ThoughtCo

26-04-2018  According to some of the first metallurgy books published in Europe, crude methods for isolating antimony metal were likely known by Italian chemists over 600 years ago. Mid-15th Century One of the antimony's earliest metallic uses came in the mid-15th century when it was added as a hardening agent in cast metal printing type used by Johannes Gutenberg's first printing presses.

Antimony Sb - PubChem

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.

Antimony Smelting - Mineral Processing Metallurgy

18-03-2016  Each ladle dips into the molten metal and, in coming out, picks up a certain quantity of the molten couverture, which, when poured out together with the metal into a hot mold, completely covers the metal on all sides. Ladling must be done rapidly for each moldful—four or five ladles to one slab of regulus according to the size of the ladle used.

Antimony and Antimony Compounds - Grund - - Major ...

Antimony metal is recovered from ore primarily by pyrometallurgical techniques. Because rich ores are becoming rare, greater recourse is being taken to intermediates in processing and metal industries. Hydrometallurgical processing is suitable for some ores containing precious metals and is used by the Sunshine Mining Co. (USA).

New method developed for producing some metals

“Antimony was a good test vehicle for the idea, but we could imagine doing something similar for much more common metals,” Sadoway says. And while this demonstration used an ore that is a sulfide (metal combined with sulfur), “we see no reason why this approach couldn’t be generalized to oxide feedstocks,” which represent the other major category of metal ores.

Antimony - an overview ScienceDirect Topics

Antimony is injected into the fresh feed, usually with the help of a carrier fluid such as LCO. If there are feed preheaters in the unit, antimony should be injected downstream of the preheater to avoid thermal decomposition of the antimony solution in the heater tubes. The effects of antimony passivation are usually immediate.

Gunshot residue - Wikipedia

Gunshot residue, also known as cartridge discharge residue, "gunfire residue", or firearm discharge residue, is residue deposited on the hands and clothes of someone who discharges a firearm. It is principally composed of burnt and unburnt particles from the explosive primer, the propellant—and possibly fragments of the bullet, cartridge case, and the firearm. Law enforcement investigators test the clothing and skin of people for gunshot residue

Extraction of Antimony

The refined metal is then ladled out and cast as " star antimony," the surface of the cakes showing a well-defined crystal structure. A method has also been suggested for refining electrolytically using an electrolyte containing antimony trifluoride with about 100 grams of free sulphuric acid and 20 grams of free hydrofluoric acid per litre.

08-02-2016  The iron precipitation method is used to produce antimony metal from concentrated antimony ores or from the crude antimony issued from the liquation process. In this process, scrap iron is added to molten Sb 2 S 3 to displace the antimony in order to form antimony metal and a matte which contains iron sulfide.
