我国非金属矿产资源丰富,种类多、储量大,资源好,出口额连年上升,1990年全国非金属矿出口创汇达8亿美元,成为国家重要创汇行业之一。但由于投资不足,非金属矿工业发展缓慢,目前加工制品主要仍是初加工产品,出口产品仍以原矿和粗精矿产品为主;非金属矿工业技术水平,与发达国家相比差距还很大,矿产品深加工技术更属落后之列。这与我国的资源优 China’s non-metallic mineral resources are abundant, with many kinds, large reserves and good resources. Its exports have risen year by year. In 1990, the country’s non-metallic mineral exports reached 800 million U.S. dollars and became one of the important foreign exchange earner industries in the country. However, owing to the lack of investment, the development of non-metallic mining industry is slow. At present, the processed products are still primarily processed products, while the exported products are still dominated by crude ore and crude concentrate products. The non-metallic mining industry is still far behind the developed countries Large, deep processing of mineral products is even more outdated. This is a resource of our country
