A New Pyrometallurgical Process for Producing Antimony ...

The refined metal is then ladled out and cast as " star antimony," the surface of the cakes showing a well-defined crystal structure. A method has also been suggested for refining electrolytically using an electrolyte containing antimony trifluoride with about 100 grams of free sulphuric acid and 20 grams of free hydrofluoric acid per litre.
