高温焙烧-磁选联合处理包钢含锌粉尘的研究王春龙1,张建良1,刘征建1,胡正文1,林祥海1,苏步新1(1.北京市北京科技大学 冶金与生态工程学院)摘 要:对转底炉处理含锌粉尘进行了实验室研究,通过设计正交试验考察了焙烧温度,焙烧时间及配煤量对含锌粉尘脱锌率,金属化率,磁选精矿产率以及铁回收率的影响.试验结果表明最佳工艺参数为:焙烧温度1 350℃,焙烧时间25min,配煤量6%.在此条件下的脱锌率和金属化率分别高达99.29%和99.68%,精矿产率为46.57%,铁回收率为95.46%.对经过最优方案焙烧并磁选......
100080, China) Abstract: The flue dust generated during electric furnace production of elemental phosphorus was investigated for the recovery of gallium. Then the flue dust was slurried with water and blended with concentrated sulfuric acid, followed by ageing. The gallium in the dust was thereby converted to soluble sulfate. The factors affecting the dust curing were investigated to understand......
