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 HAsO42−) (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 Pb5(AsO4)3Cl
- Olivenite Cu2(AsO4)OH
