Stone is a kind of biological non-toxic, harmless and biological activity of the compound has a mineral or medicinal rocks. Often in the stone's rock, acid magmatic rocks. In addition to the common chemical constituents of stone Ca, Mg, Si, Al, Fe, K, Na, there are a few rare element, rare earth elements, radioactive elements. Stone with adsorption, solubility, PH adjustment, biological activity and mineralization of the properties. Stone can absorb free metal ions in water. Stone containing about 15% Al2O3, is a typical amphoteric oxide, in aqueous solution react with a base case lower stone PH, PH acids react to improve the value of the function of a two-way PH adjustment. By the blisters had stone, could extract useful organisms on the human body and major elements K, Na, Ca, Mg, P and Si, Fe, Zn, Cu, Mo, Se, Mn, Sr, Ni, V, Co, Li, Cr , I, Ge, Ti and other trace elements. Stone in the capacity of the aqueous solution is also essential amino acids the human body. 
 Stone is mainly used in the current health care, food, beverage and water purification, sewage treatment, antiseptic, deodorant, preservation, decontamination, porcelain making and planting and breeding industry and other fields.
