The Glass of Antimony: Operative and Alchemical Considerations

 · This is due to the sulfur in the stibnite being exchanged with oxygen from the air, hence the need for constant stirring, as it is the exposure to not only heat but also air that makes the " roasting " possible. Needless to say, I held my breath each time I .

Metals | Free FullText | OneStep Extraction of Antimony in Low .

 · Experimental results indied that antimony recovery improved firstly and then decreased steadily as α salt increased from to Insufficient dosage of molten salt (α salt = ) results in a poor fluidity of reaction melt in low temperature. As a result, the settling and accumulating of antimony particles is also inefficiency.

Antimony: will China continue to control supply?

 · Nils Backeberg, senior analyst in metals and technology materials at Roskill Information Services, explains that in 2011, the price of antimony spiked, but due to an overall decline in consumption, the price decayed slightly before experiencing an uptick in 2016 when hit around 8,000 per ton. It has since remained around this price.
