我国矿产资源总量丰富,但人均占有量少,总体属于矿产资源相对匮乏的国家。矿产资源种类较为齐全,但大宗矿产优势矿产多为短缺或探明储量不足,需要长期依赖进口。此外我国贫矿多、富矿少,低品位难选冶矿多、高品位易选冶矿少,共生矿床多、单一矿床少,中-小型矿床多、大型-超大型矿床少。这就使得对矿产资源的综合利用研究具有很强的现实意义。我国现开发利用的矿产中有近2/3矿产部分或全部来源于共、伴生矿产资源。鉴于我国矿产资源“四 The total amount of mineral resources in our country is rich, but the per capita possession amount is small, which belongs to the country where the mineral resources are relatively scarce. The types of mineral resources are more complete, but the bulk of the mineral resources of large or shortage of proven reserves, the need for long-term dependence on imports. In addition, China has more lean mines, fewer rich mines, more low-grade refractory smelters, less high-grade and easy-to-use mined ore, more symbiotic deposits, fewer single deposits, less medium- and small-sized deposits, and large- and large-superlarge deposits. This makes the comprehensive utilization of mineral resources research has a strong practical significance. Nearly two-thirds of the mineral resources currently exploited in our country are derived, in part or in total, from co- and associated mineral resources. In view of China’s mineral resources ”four
