矿物原料资源对于每个国家的经济,对于发展工业,首先是发展重工业来说,起着极重大的作用。矿产是我们社会主义国家赖以富强的主要源泉之一。每年可以从地下采出几十亿吨燃料,实际上我们就是以这些燃料来建立工业、运输业和农业的动力基地,以及满足城市和工业中心对燃料的需要。从地下也可以采出金属原料,有了这些金属原料,才能获得愈来愈多的黑色金属、有色金属、稀有金属和贵重金属。每炼1吨生铁至少要采出2—3吨铁矿石,炼1吨铜至少要有100吨左右的铜矿石;炼1吨钼平均需要开采和加工达1000吨矿石,而1吨黄金则需要开采
Mineral raw material resources play an extremely important role in each country’s economy and in the development of industry, first of all, the development of heavy industry. Minerals are one of the main sources of our rich and strong socialist countries. Each year, billions of tons of fuel can be produced underground. In fact, we use these fuels to establish industrial, transportation, and agricultural power bases and meet the fuel needs of cities and industrial centers. Metal materials can also be produced from the ground. With these metal materials, more and more ferrous metals, non-ferrous metals, rare metals and precious metals can be obtained. 1 ton of pig iron per smelter should produce at least 2-3 tons of iron ore, and 1 ton of copper should contain at least 100 tons of copper ore; refining 1 ton of molybdenum requires an average of 1,000 tons of ore to be mined and processed, and 1 ton of gold.
