硫铁矿烧渣综合利用试验研究

针对西北某硫铁矿烧渣的具体情况,试验研究了影响硫铁矿烧渣磁化焙烧-磁选的主要因素。结果表明:采用挥发份较高的新疆哈密烟煤,当焙烧温度为700℃、焙烧时间为30m in、煤粉配比为6%时,可获得铁精矿品位为63.08%、回收率为75.78%的技术指标,试验取得了较为满意的结果。

Experimental Research on Comprehensive Utilization of Roasted Pyrit

Target at specific circumstances of a roasted pyrite in northwestern region of China,the major factors influencing magnetic roasting and magnetic separation were researched.Results showed that under the conditions of using bituminite containing higher content of valatile matter from Hami,Xinjiang Uygur Autonomous Region,when the roasting temperature is 700℃,the roasting time is 30min,and the proportioning of coal fines is 6%,an iron concentrate of 63.08% Fe with a recovery of 75.78% can be produced.The technical indexes obtained by laboratory tests are comparatively satisfactory.
