Arsenates

Group of minerals that are compounds of one or more metallic elements associated with the arsenate radical (AsO4). The arsenates, together with the related vanadates, are classified in the phosphates group.
Most arsenates are heavy, and none are hard. They are usually brittle and occur in small crystals or compact aggregates.
