化学矿有磷矿、硫铁矿、硼矿、钾盐矿、蛇纹石、天青石、化工用石灰石、明矾石及天然碱等20余类,是生产化工产品的基本原料。这类天然产品或经过富集的天然产品,均属非再生资源,同一产品化学组成复杂,杂质变异性大,随地质生成条件而变化,大部分产品属难熔矿物;产品批量大,为大宗矿产品。此外,我国主要化学矿产品在资源储量上、质量上不及美、苏两国,与我国化工生产需要尚存在一定的差距。因此,在我国化学矿资源的利用问题上,一直存在着化工生产需要与地质资源及质量的矛盾。这些特点,都直接影响到化学矿标准的 There are more than 20 chemical ore mines, such as phosphate rock, pyrite, boron mine, potash mine, serpentine, celestine, chemical limestone, alumite and trona, which are the basic raw materials for the production of chemical products. Such natural products or enriched natural products are all non-renewable resources. The chemical composition of the same product is complex, and the variability of impurities is large. It varies with the conditions of geological formation. Most of the products are refractory minerals; Mineral products. In addition, China’s major chemical mineral products are inferior to the United States and the Soviet Union in terms of resource reserves and quality, and there is still a certain gap between China’s chemical production needs. Therefore, there is always a contradiction between chemical production needs and geological resources and quality in the use of China’s chemical ore resources. These characteristics have a direct impact on the chemical ore standard
