Antimony Production Process - wallpaperpoets.be

Antimony Production The primary production and metallurgy of antimony has been reviewed by Anderson (2012) [1]. However, in order to discuss the secondary production of antimony from industrial residues, a short overview must be given here of the main production routes, process residues, and metal-containing waste streams. The main pyro- and.

Antimony | Minerals Education Coalition

Antimony is also used for pigments in plastics, paints, rubber, and for a wide variety of minor uses, including medicines, fireworks and others. Antimony oxide is a brilliant yellow color, accounting for much of the pigment use. A tiny amount of highly purified antimony metal is used in the computer industry to make semiconductors.

ANTIMONY PRODUCTION BY CARBOTHERMIC REDUCTION …

production of noxious antimony vapors and sulfur dioxide (SO 2) is unavoidable; therefore, this process has serious problems of atmospheric contamination. The direct reduction of metal sulfides in the presence of lime is a viable alternative method to produce metal values without emitting the contaminant sulfur dioxide. Several studies have been

Antimony - an overview | ScienceDirect Topics

Antimony in its elemental form is a silvery white, brittle, fusible, crystalline solid that exhibits poor electrical and heat conductivity properties and can sublimate upon heating. A metalloid, antimony resembles a metal in its appearance and in many of its physical properties, but does not chemically react as a metal.

The stibnite concentrates are then fumed to a crude oxide that is either fumed to a finished oxide or reduced to metal and then fumed to finished oxide. Tetrahedrite concentrates are usually leached in alkaline solutions that are electro-won to recover antimony metal or oxidized to sodium antimonite.
