我国煤炭资源丰富,而高硫煤即占四分之一。山西、四川、河南等地都有大量的煤 系硫铁矿矿床。我国煤系硫铁矿的储量约占硫铁矿总储量的一半,是一巨大的潜在资源。硫铁矿是黄铁矿、白铁矿、磁黄铁矿的统称,而在煤系硫铁矿中,大部是黄铁矿,且多呈半自形——它形晶粒状集合体形式产出。 在煤系硫铁矿的选矿中,选煤脱硫与回收黄铁矿是紧密相关的,因煤和硫铁矿的可 Our country is rich in coal resources, while high-sulfur coal accounts for a quarter. Shanxi, Sichuan, Henan and other places have a large number of coal-based pyrite deposits. China’s coal-based pyrite reserves account for about half of the total reserves of pyrite, is a huge potential resource. Pyrite is pyrite, white iron ore, pyrrhotite collectively, and in coal pyrite, most pyrite, and mostly semi-self-shaped - it shaped grain-like aggregates Form output. Coal pyrite in the dressing, coal desulfurization and recovery of pyrite is closely related to the coal and pyrite can be
