Minerals: Vanadates.

1. Introduction. Vanadates are a source of vanadium (V) which is a putting green element in the earths crust but it is only clear in small quantities. Vanadium is apply in exercise to strengthen steel, it is employ in making an iron cheapen called ferrovanadium. Vanadium does not readily react with any just about separate chemicals but it ignore absorb neutrons; it can be used in nuclear reactors. South Africa has one of the richest sources of minerals guiding vanadium. Vanadates are tap for different important elements which include zinc, copper, authorise and uranium. Uranium is used in nuclear power plants as a heat up source as it is radioactive. 2. mineral identification. Mineral class and sub-class: Vanadates are a sub-class of the Phosphates class of minerals. Minerals in the class of phosphates have the same cosmopolitan chemical shape which is: (AO4)?. The A stands for the either Vanadium (V), atomic number 51 (Sb), Arsenic (As) or Phosphorous (P), all these elements are interchangeable. legion(predicate) phosphates create solid solution series between the V, Sb, As and P. A solid solution series occurs when two or much structurally identical minerals can interchange elements inside their chemistries without dramatically altering the crystal structure. they can occur in a series right next to each other in nature.

Phosphates have a generally high denseness and can range in hardness from 4 to 7 on the Mohs scale of hardness. They form many a(prenominal) different minerals and core with other ions like hydroxide convocations, uranyl separates, water and halogens. The (AO4) group forms a tetrahedro! n with 4 oxygen anions surrounding the (A) cation making a real dense crystal structure. Vanadates are any minerals that contain the (VO4)? group and there are about 50 vanadate minerals that proceed to many different groups called the apatite, adelite vanadium oxysalt and descloizite groups.
