1. Background. Antimony is a silvery, white, brittle, crystalline solid that exhibits poor conductivity of electricity and heat. It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C. Antimony metal, also known as 'regulus', melts at 630 °C and boils at 1380 °C.Antimony and the natural sulfide of antimony were known as early as 4000 BC.

Heavy media separation is a gravity separation process that crush ores into a certain size, and make the density of the fluid heavier than water (that is heavy medium). According to the Archimedes' principle of buoyancy, when density is less than media, ore particles will float; when the density is greater than media, ore particles will sink.
