| 摘 要： | 为提高硫铁矿烧渣的铁品位，实现硫铁矿资源的充分利用，对W（S）约为17％和21％的低品位硫铁矿分别进行了实验室和工业精选试验。工业试验结果表明，精选后的硫精矿平均W（S）为51．09％，硫回收率达90．85％；该精矿经沸腾焙烧后，获得平均W（Fe）65．11％、W（S）0．21％的铁精矿，符合炼铁原料标准。

| Abstract: | Laboratory and industrial experiments of concentration of low-grade pyrite containing 17%and 21%S were carried out,respectively,for increasing iron grade in pyrite cinder and realizing full utilization of pyrites resource. The industrial experiments showed that pyrite concentrate containing 51.09%S was obtained by floatation with 90.85%S recovery.Roasting of the concentrated pyrite produced a cinder containing 65.11%Fe and 0.21%S on an average,which was up to the iron-making raw material specification. |
