Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table).Antimonyexists in many allotropic forms. It is a lustrous, silvery, bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite.

This method has many features, high efficiency, energy saving, and environment protection, which can make the low-grade ore enrichment advance. After gravity separation, the antimony will bepurified by floatation. So the processingmethod of HOT mining is gravity separation- flotation process.

Antimony sulfide imported from, at different times, China, South Africa, andSouth America was processed in the North-East of England from about 1870 to 2003. The process workers in North-East England have been studied at different times, notably by Sir Thomas Oliver in 1933, and by the Newcastle upon Tyne University Department of Occupational Medicine on later occasions.

Antimony-Antimony-Properties and reactions: The most stable form of elementalantimonyis a brittle, silvery solid of high metallic lustre. Electrolytic deposition ofantimonyunder certain conditions produces an unstable, amorphous form called “explosiveantimony,” because, when bent or scratched, it will change in a mildly explosive manner to the more stable, metallic form.

Antimonyis sometimes found in pure form. It is also obtained from the mineral stibnite (antimonysulfide) and commonly is a by-product of lead-zinc-silver mining. Otherantimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.
