The metallurgy of antimony - ScienceDirect
In ancient times, in extracting antimony from sulfide ore by the addition of iron, a starlike fern shaped crystalline pattern appeared during the course of solidification. This was dubbed the “Philosophers Signet Star” in 1610 and until recently the shape of these stars had commonly served to indicate the grade of the metallic antimony.
The Metallurgy of Antimony | Request PDF
The process of reductive smelting of the antimonate concentrate on black antimony was carried out in an oven with silicate heaters in alundum crucibles with batches of charge of 100–150 grams.
Antimony distribution and environmental mobility at an ...
The smelter initially used four cast iron retorts and wood-fired furnaces to melt the ore, which was mixed with scrap iron to produce 90–92% pure antimony (Johnston, 1993). In 1885, the smelter was redeveloped with a large sorting and crushing facility and a more complex smelting process.
[PDF] One-Step Extraction of Antimony in Low Temperature ...
A new process for one-step extraction of antimony in low temperature from stibnite concentrate by reductive sulfur-fixation smelting in sodium molten salt, using iron oxide as sulfur-fixing agent, was presented. The influences of molten salt addition and composition, ferric oxide dosage, smelting temperature and duration on extraction efficiency of antimony were investigated in details ...

Jan 16, 2013 · Antimony is used in lead bullet alloys - IIRC, linotype is about 84% lead, 12% antimony and the balance is tin. One issue with melting and casting is that when the metal does finally melt, it does so immediately and you can have a potentially dangerous situation if you arent prepared for …

Nov 28, 2016 · Antimony has a melting point of 631°C compared with copper’s 1,085°C and iron’s 1,540°C melting points. The ‘holy grail’ would be steel production as it is the number one industrial source of carbon dioxide, the main greenhouse gas.
Behavior of Tin and Antimony in Secondary Copper Smelting ...
In this study, the distribution of tin and antimony between metallic copper and iron-alumina spinel saturated iron silicate slag, with 0–5 wt % K 2 O, was experimentally studied. The experimental temperature was selected as 1300 °C, which is in the same range as processing temperatures in industrial operations.
New method developed for producing some metals | MIT News
Aug 24, 2016 · The MIT researchers were trying to develop a new battery, but it didn’t work out that way. Instead, thanks to an unexpected finding in their lab tests, what they discovered was a whole new way of producing the metal antimony — and potentially a new way of smelting other metals, as well.

Smelting - Wikipedia
Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a stone reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a …
