硫铁矿是我国目前生产硫酸的主要原料。我国硫磺和硫铁矿资源虽然丰富,但因多是复合矿石,给工业利用带来很大的困难。工业生产的发展对地质勘探、开采、可选性评价等方面的要求愈来愈合于生产的实际。目前做为硫的来源,主要有自然硫、黄铁矿、磁黄铁矿及从石油炼制中回收的硫磺等。我国当前大量进行的地质勘探和开采利用的主要是黄铁矿中的硫。
Pyrite is the main raw material for producing sulfuric acid in our country. Although rich in sulfur and pyrite resources in our country, the ore is mostly complex ore, which brings great difficulties to industrial utilization. The requirements of the development of industrial production for geological prospecting, mining, optional evaluation and so on are more and more close to the actual production. Currently as a source of sulfur, there are mainly natural sulfur, pyrite, pyrrhotite and sulfur recovered from petroleum refining. The vast amount of sulfur in pyrite currently being used in geological prospecting and exploitation in China is predominant.
