Description

Inorganic salt industry uses raw materials are of natural resources and some work, agricultural waste, and by-products. Natural resources and s solid, liquid and gas cent. Solid resources is all sorts of minerals mainly(see table); Liquid resources have brine, and salt lake water and sea water; Gas resources have carbon dioxide, hydrogen sulphide, air, etc. More than *0% of the inorganic salt industry products derived from natural resources. Inorganic salt industry is based on the mineral processing as the basis, so closely related with mineral exploitation. Mineral development is very complex process, suffer many limitations , including ore-forming geological conditions, development techology economic conditions, including ore-forming geological conditions, development technology economic conditions, and the consumer market, mineral products resource to rational use and so on, Some product processing technology on ore grade and for a certain impurity content have special limit, it must choose suitable for processing technical requirements of resources, such as natural resources short of asks, they must be dressing. Social need is also an unavoidable factors, in the above conditions are satisfied circumstances, such as social need urgent, even if is also have advantage of lean way. Like many lov grade of boron mine, phosphate rock, chromium ore, XIaShi, Kaolin, chemical processing, in many countries has realized industrializaion.Resources development the final index is economic benefits, also want to consider the comprehensive utillzation of mineral, in order to achieve full use of resources and for the purpose of environmental protection.
