extraction of antimony from its ore

The extraction of Antimony from its ore LEVITYThe crude ore (reduced to pieces of about the size of a nut but not into powder) is placed in a crucible having a hole of 5 mm of diameter at its bottom. A metallic wirenetting is placed around the crucible. Acting as a screen, it will "break" the flames coming from the two burners.Extraction of AntimonyAntimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated.
