Selective Separation and Recovery of Valuable Metals by Vacuum

This paper reviews the state-of-the-art technologies for the antimony separation and recovery from refractory ores and metallurgical residues.Furthermore, introducing recovery techniques in industries where antimony is released in wastewaters leads to more responsible production routes. In this work, electrodeposition is employed to recover the antimony present in a secondary waste effluent of the copper electrorefining that is highly concentrated in hydrochloric acid.Process flowsheet development for recovering antimony from

Minerals Free Full-Text Preparation of Antimony

Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the The history of antimony goes back to as early as 3100 BC, when it was used by the Egyptians as cosmetic in the form of black Sb 2 S 3 [].Antimony was later used by alchemists in the form of antimony oxychloride SbOCl, which acted as a powerful emetic and thus became known as “mercury of life” or “algarot” [].The etymology of the current Antimony Recovery from End-of-Life Products and Industrial

Caption. Figure 1: In this liquid metal battery, the negative electrode (top) is a low-density metal called here Metal A; the positive electrode (bottom) is a higher-density metal called Metal B; and the electrolyte between them is a molten salt. During discharge (shown here), Metal A loses electrons (e-), becoming ions (A+) that travel throughAntimony is a silverly, lustrous grey metal that exhibits poor heat and electrical conductivity. It is relatively soft, measuring only 3.25 on Moh's scale of mineral hardness. Known as "stibium" in classical Latin, antimony is represented by the chemical symbol Sb.

A hydrometallurgical process for the separation and recovery of antimony

Fig. 1 shows this new hydrometallurgical process for antimony extraction. This process involves chlorination–oxidation leaching that inhibits the formation of most impurities in solution. By controlling the leaching potential, S 2 − in stibnite is oxidized to elemental sulfur, and antimony becomes SbCl 3 in solution.
