Minerals are the constituents which remain as ash after the incineration of plant and animal tissues. They may be divided into two categories; main elements (Ca, P, K, Cl, Na, Mg) and trace elements (Fe, Zn, Cu, Mn, I, Mo, etc.). According to their biological roles, they may also be divided into essential elements, for which the biological roles are known; nonessential elements, with unknown functions, if any; and toxic elements, which may be ingested through food or water or absorbed from the air.
