Arsenate mineral

Arsenate minerals usually refer to the naturally occurring orthoarsenates, possessing the (AsO₄)^3- anion group and, more rarely, other arsenates with anions like AsO₃(OH)^2- (also written HAsO₄^2-) (example: pharmacolite Ca(AsO₃OH)^.2H₂O) or (very rarely) [AsO₂(OH)₂]^- (example: andyrobertsite). Arsenite minerals are much less common. Both the Dana and the Strunz mineral classifications place the arsenates in with the phosphate minerals.

Example arsenate minerals include:

• Annabergite Ni₃(AsO₄)₂·8H₂O
• Austinite CaZn(AsO₄)(OH)
• Clinoclase Cu₃(AsO₄)(OH)₃
• Conichalcite CaCu(AsO₄)(OH)
• Cornubite Cu₅(AsO₄)₂(OH)₄
• Cornwallite Cu²⁺₅(AsO₄)₂(OH)₂
• Erythrite Co₃(AsO₄)₂·8H₂O
• Mimetite Pb₆(AsO₄)₃Cl
• Olivenite Cu₂(AsO₄)OH
