THE MINERAL NATIVE ANTIMONY - galleries.com

Antimony does not often form in its elemental state and is far more common in sulfides and sulfosalts such as stibnite, tetrahedrite, bournonite, boulangerite and jamesonite.It is also found in some oxides such as valentinite, stibiconite and senarmontite Due to the abundance of these antimony bearing ores and the rarity of native antimony, it is never an important ore of itself.

Terminology — US Antimony

They are generally either senarmontite and/or valentinite that are both antimony trioxide with a theoretical maximum antimony content of 83.53%. Gravity concentrates are typically much lower grade than sulfide concentrates and are in the 25-40% antimony content. Recoveries from oxide mills are generally less than 50%.

Antimony in alchemy

A survey of antimony and its compounds in alchemy. Alchemical symbol for antimony. Derivation of name : Middle English antimonie, from Medieval Latin antimonium, perhaps from Arabic al-'itmid : al-, the + 'itmid, antimony (perhaps from Greek stimmi).
