Antimony Recovery from End-of-Life Products and Industrial …
Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame …

Oxidizing Roast; Stibnite the Antimony Mineral
After grinding, it had a jet-black color. A chemical analysis gave 71.66 per cent, antimony and 0.96 per cent insoluble. Calculating the antimony as the sulphide gives 100.3 per cent. Sb2S3; the excess over 100 is probably due to the presence of a small amount of metallic antimony. The roasting furnace used was of the electric resistance type ...

Antimony Metallurgy
Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. Valentine of Germany.

Antimony Processing: Unlocking the Potential of a Versatile Element
Antimony compounds are employed in the glass and ceramics industry. Antimony oxide (Sb2O3) acts as a decolorizing agent in glass manufacturing, helping to remove the green or yellow tint caused by iron impurities. It is also used in the production of opalescent glass, which displays a milky or iridescent appearance.

Swedish roasting process solves problems with contaminated ores
The roasting process, also known as 'calcination', leaves behind a 'calcine' of iron oxide cinders. This material can be used in steel production. A requirement for this, however, is that the iron oxide is not contaminated with volatile impurities such as arsenic, antimony, bismuth and lead.

Recovery of gold from sulfide refractory gold ore: Oxidation roasting
In the air oxidation roasting process, the major components (FeAsS, FeS 2) of the sulfide refractory gold ore would convert into iron oxides, arsenic oxides, sulfur oxides, sulfate and arsenate (Mikhail and Turcotte, 1992). Especially, arsenic is easily oxidized to As 2 O 3 or As 2 O 5, when heats in air, and As 2 O 3 is easy to volatilize.

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 residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide were …
