Arsenopyrite Mineral | Uses and Properties

This is a characteristic of many arsenic minerals and a clue that arsenopyrite might be present. Arsenopyrite often oxidizes to form scorodite, a hydrated iron arsenate mineral with a chemical composition of FeAsO 4. 2H 2 O. Scorodite often weathers to limonite, an amorphous, hydrated iron oxide of variable composition. In areas where mining ...

Precipitating arsenic (As) as Fe-As minerals by stepwise neutralization is a common practise to sequester As from acidic industrial effluent (e.g., acidic uranium mill effluents). Despite their importance, the evolution of specific Fe-As minerals during the neutralization process and their stability after formation is poorly understood.

Realgar - Wikipedia

Realgar, α-As 4 S 4, is an arsenic sulfide mineral, also known as "ruby sulphur" or "ruby of arsenic". It is a soft, sectile mineral occurring in monoclinic crystals, or in granular, compact, or powdery form, often in association with the related mineral, orpiment (As 2 S 3).It is orange-red in color, melts at 320 °C, and burns with a bluish flame releasing fumes of arsenic and sulfur.

Arsenic is an elusive element, with a mysterious ability to change color, behavior, reactivity, and toxicity. For exam-ple, two arsenic sulfide minerals, red-colored realgar (As 4S 4) and bright yellow orpiment (As 2S 3), were described by the ancient Greeks, but they considered them to be two entirely different substances (Irgolic 1992).
