Antimony Recovery from End-of-Life Products ... - SpringerLink

The recovery of traces of gold and antimony from these ores is only interesting for waste products, as this does not cause losses in the recovery of the main metal. The processing of the second group of ores (2), usually requires changes in the flowsheet in order to ensure the recovery of both the gold and antimony fraction.

Refractory Gold Ore Treatment Methods

An 80 per cent gold recovery was made by the method of treatment described. It is generally known that antimony can be readily volatilized, and by roasting stibnite (Sb2S2) in an oxidizing atmosphere, antimony oxide can be driven off and condensed.

Antimony trioxide - Wikipedia

Antimony(III) oxide is an amphoteric oxide, it dissolves in aqueous sodium hydroxide solution to give the meta-antimonite NaSbO 2, which can be isolated as the trihydrate. Antimony(III) oxide also dissolves in concentrated mineral acids to give the corresponding salts, which hydrolyzes upon dilution with water.

Antimony - Wikipedia

Antimony is a stone 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.

The Costerfield Gold-Antimony Field is part of a broad gold-antimony province mainly confined within the Siluro-Devonian Melbourne Zone. Although antimony commonly occurs in an epithermal setting (in association with silver, bismuth, tellurium and molybdenum), the quartz-stibnite-gold narrow veins of the Melbourne Zone are mesothermal-orogenic and are part of a 380 - 370 Ma tectonic event.
