对川南某地煤系硫铁矿进行综合利用新工艺研究.通过全浮选流程选别,可得到含硫大于49％的高硫精矿.硫精矿沸腾焙烧制酸后,得到残硫小于0.2％、含铁大于64％的硫酸渣,可以用作炼铁原料,浮选尾矿可以作为建筑材料回收利用.%A study was made on new technology for comprehensive utilization of the coal derived pyrite of Sichuan south. The pyrite concentrate which is cleaned to the S grade of over 49 % by the process of flotation is used to make acid. The TS content and Tfe content of the acid making slag are less thanO. 2%and more than 64% respectively. Therefore, the pyrite slag can be used as raw material for iron making, the flotation tailings can be reutilized as constructional material.
