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.
