antimony concentrates process

Process flowsheet development for recovering antimony from ...

Aug 01, 2013  To have an effective and efficient leaching of antimony from its minerals (e.g. tetrahedrite), it would be beneficial to the leaching process if the mineral particles of the concentrate are finely ground prior to the leaching step (Filippou et al., 2007, Awe et al., 2010, Awe and Sandström, 2010b). Moreover, high concentration of the alkaline ...

Antimony - Wikipedia

Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was

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. However, there are companies in the United States that produce antimony ...

Antimony recovery from complex copper concentrates through ...

During smelting of copper concentrates, arsenic is easily removed into the offgas while antimony is not readily removed due to its lower partial pressure and high affinity for liquid copper. Therefore, removal of these impurities at an early stage of processing will be beneficial for the copper making process.

Extraction of Antimony

Extraction of Antimony. Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or ...
