Slags, antimony-smelting Substance resulting from the smelting of materials containing antimony obtained from primary and secondary sources and including recycled plant intermediates. Consists primarily of antimony and SiO2 and may contain other residual non-ferrous metals and their compounds.
A large amount of solid waste has been produced by the antimony smelting process in the "World Capital of Antimony", Xikuangshan area in China.

Therefore, the most promising process for antimony smelting is the low-temperature process. A proposed process exists for recovering antimony under low temperature consisting of the following steps: feeding ﬂux, stibnite-containing feed, and a sulfur-ﬁxing agent,
Antimony (Sb) is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification.
Other process used for a long time is the Wohlwill Process and is considered as the second part of the Miller process due to refine its product. This is an electrolytic process based on the dissolution of gold in an acid bath prepared with chlorine gas and hydrochloric acid.
The material they were using, antimony sulfide, is a molten semiconductor, which normally would not allow for the kind of electrolytic process that is used to produce aluminum and some other metals through the application of an electric current.
Lead for recycling may be in the form of scrap metal (roofing sheet, for example), or compounds of lead, such as the pastes from lead-acid batteries. Clean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ores.

The antimony smelting techniques that have been developed in Xikuangshan are typical of smelters in China. Traditional smelting methods have been improved since the 1940s, but several novel achievements have been introduced in recent years.
The major hazards are exposure to ore dusts during ore processing and smelting, metal fumes (including lead, arsenic and antimony) during smelting, sulphur dioxide and carbon monoxide during most smelting operations, noise from grinding and crushing operations and from furnaces, and heat stress from the furnaces.
MIT's accidental smelting discovery unlocks the potential of antimony Nov 28, 2016 Indeed, it was the discovery of the Hall-Héroult electrolytic process more Use of antimony trioxide as a flame-retardant mineral, meanwhile,
Thus the composition of antimony smelting slag is chemically complex and may contain the antimony oxide losses and antimony compounds produced by redox reactions in the process of smelting under alkaline conditions.
While antimony remains a metal of limited use in the wider world, the researchers believe the same process could be applied to smelting and the production of other more economically important ...
The main purpose of this study is to characterize and separate antimony from a stibnite concentrate through a low-temperature sulfur-fixing smelting process. This article reports on a study conducted on the optimization of process parameters, such as flux and zinc oxide weight percentage, in ...
