矿产资源的丰富程度,是衡量各国实力的综合指标之一。 我国素以“地大物博”著称,但是也存在着部分矿种富矿少、贫矿多、伴生矿多,某些矿种稀缺等问题。不过,只要认真坚持“开源与节流并重”两条腿走路的方针,我们对我国矿产资源开发的前景还是乐观的。“开源”,就是扩大矿物原料的来 The richness of mineral resources is one of the comprehensive indicators to measure the strength of each country. China has always been known as “big land, material and abundant resources”, but there are also some problems such as low ore deposits, poor ore, associated minerals, and scarcity of certain minerals.
