Pliny the Elder named the metal stibium, and the eighth century Arabian alchemist Geber (Jabir) referred to it as "antimonium," from the Greek anti (against) and monos (alone), in ...
Antimony | SbAntimony is a silverywhite metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in the United States that produce antimony ...

Separation the following pictures show the main steps of a metallurgic operation which will provide purified antimony metal from its ore although the alchemical operation is very similar same tools and actions important differences exist, mainly concerning the nature of the prima materia
USAAntimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable byproducts. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.

Antimony MetalAntimony Metal What you need to know. Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis.
