The Arsenate subclass (and to a lesser extent the Vanadate Subclass) of the Phosphate Class almost perfectly mirrors the true phosphates in many ways including structure, diversity and properties. Identifying these arsenate-bearing minerals is essential to exploration. 747 Arsenate is mainly adsorbed in the BM and BB geometries, as determined by in situ 748 ATR-FTIR and XAFS (Carabante et al., 2010; Neupane et al., 2014). Ferric arsenate minerals are important because, for example, scorodite is the least soluble arsenate phase in many mine tailings systems, and it controls arsenic releases to tailings pore water and to the environment (e.g., Langmuir et al. This unique combination of the elements silicon and oxygen bonds with a bewildering array of other elements to form the large number of silicate minerals. Influence of arsenate adsorption onto Fe- and Al hydroxide mineral surfaces on microbial arsenate reduction rates .

Vanadate Minerals. The arsenate minerals, which are salts of arsenic acid, contain arsenate groups (AsO 4) in which four oxygen (O) atoms are arranged at the corners of a tetrahedron about a central arsenic (As) atom. The final regulatory action cancelled the registration of lead arsenate formulations, resulting in a ban on the use of lead arsenate as a pesticide, including import, manufacture, formulation, distribution or marketing of such pesticide in Peru.
