1, Comprehensive utilization of the mineral resources is a prerequisite for geological prospecting

To carry out geological prospecting, firstly, we must solve the issue what is “mine”? The so-called mine is made up from available ore, which stipulate by mineral industry and usually was been indicated by ore grade. Ore grade means enrichment of the useful component and unit level in the metal deposit and non-metal deposit (such as apatite, potassium salt, fluorite etc). Ore grade determines the level of development and utilization of mineral resources in aspect of the size of value, direction of production and utilization and process flow of technology and so on. Ore grade level of raw material indicates the level of richness and poverty of ore. However, the ore grade level of preparation concrete reflects the recycle of certain content. The industrial ore grade is an important indicator of industrial minerals. It changes with the national economic policy, the improvement of science and technology, the geology condition of ore deposit and demand of ore. For example, in early 19 century, the cooper only can be extracted when it contain the cooper element more than 10%.but now porphyry copper only contains copper element 0.5% and it has been extract in large scale. Comprehensive utilization of mineral resources, not only can debase the ore industrial grade ,increase the ore capacity, but also can be integrated collection of associated mineral resources, to discover the new mineral resources, expand the scope of prospecting, reduce waste, thereby enhancing the economic benefits, social protocols and environmental benefits. 

2, Comprehensive utilization of mineral resources is the important content of geological prospecting evaluation.

General provisions of mineral geology exploration says that mineral geology explore must adhere to the principle of “comprehensive survey, comprehensive evaluation.” Make full use of and protect mineral resources. The survey and comprehensive evaluation of mineral resources include that, firstly, identify the type, content, occurrence, distribution of associated components; Identity the mineral structure and structural characteristics; research the comprehensive recycling possibility of associated components. Comprehensive grade decides the subject and circulates the reserves. Secondly, recycle and reuse the waste, waste water, waste gas, waste heat, pressure which formed in the production project in the future, such as complete crushing plant, jaw crusher, impact crusher, cone crusher, vibrating screen, belt conveyor etc. thereby increasing the amount of resources available.
 
3, Current resources situation demands Comprehensive utilization of mineral resources
 
On one hand, China is characterized by much lean ore, much associated mineral resources. The geology conditions decide that only carry out the policy of comprehensive utilization of mineral resources can make better use of mineral resources. On the other hand, after many years of comprehensive development and utilization of mineral resources, we conclude that there exists a lot of low-grade, refractory resources haven’t been extracted due to the shortage of technical and economic conditions in the past years and a large number of secondary resources in the remnant ore, tailings and waste which formed in the course of extraction can be recycle and reuse by comprehensive utilization. Thirdly, the social progress and implement of the scientific concept of development demand change the long-standing extensive development and utilization of mineral resources. Comprehensive utilization of mineral resources can expand the resources origin, reduce the cost of development and provide a resources safeguard to China’s sustainable economic and social development.
 

Comprehensive utilization of mineral resources is both re-use resources and reduce expenditure. To solve the problem of safe supply and ensure resources, we must be balance to prospect according to the geology and be comprehensive to use the mineral resources. In particular, we should place the comprehensive utilization of mineral resources in a prominent position, which is a long-term solution of our country’s resources protection and rational utilization.
