Antimony | SpringerLink
Antimony (Sb) is a naturally occurring metalloid element. It can exist in a variety of oxidation states (−III, 0, III, V), but is mainly found in two oxidation states (III and V) in environmental, biological and geochemical samples [].The abundance of Sb in the Earth's crust is in the order of 0.2–0.3 mg kg −1 [].The concentration of Sb in soils is …
Antimony: Mineral information, data and localities.
Member of: Arsenic Group. Name: From the medieval latin 'antimonium', originally applied to stibnite. The etymology is uncertain; the popular etymology, from ἀντίμοναχός anti-monachos or French antimoine, still has adherents; this would mean "monk-killer", and is explained by many early alchemists being monks, and antimony being ...

The exposure to and health effects of antimony
INTRODUCTION. Antimony (Sb) (atomic number 51; atomic mass 121.75 g/mol; density 6.684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3).The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure …

AG Autogenous Grinding
In conventional mills the diameter of the mill is smaller than its length. In autogenous mills the diameter is greater than the length. They can be as much as 40+ feet in diameter. Patented in 1959, AG Mills are not so popular any more. This large diameter of mill is required to achieve the impact necessary to grind the ore.
