化学矿是化学工业的矿物原料,约有十多个品种,其中磷矿石、硫铁矿、硼矿、钾盐矿、石灰石矿等在工农业生产中起着重要的作用。它们不仅产量多。而且直接影响磷肥、硫酸、硼砂、钾肥、纯碱等基本工业的发展。因此,化学矿的标准化与上述这些工业产品的标准化,有着非常密切的关系。化学矿专业是我国划分矿业专业的一种特殊的分类形式。它的标准化专业技术归口的划分,在各国标准化专业分类上也是独特的。化学矿产品既有金属矿如硫铁矿,也有非金属矿
Chemical ore is the mineral raw material of the chemical industry, and there are about a dozen varieties. Among them, phosphate rock, pyrite, boron ore, potash ore and limestone mine play an important role in industrial and agricultural production. They not only yield more. But also directly affect the development of phosphate, sulfuric acid, borax, potash, soda ash and other basic industries. Therefore, the standardization of chemical mines and the standardization of these industrial products have a very close relationship. Chemical mine is a special classification of mining industry in our country. Its standardization of technical expertise at the division of the national standardization of professional classification is also unique. Chemical minerals both metal ore such as pyrite, but also non-metallic mineral
