摘要
以红土镍矿为原料,用热重分析（TG）和X射线衍射分析（XRD）等方法,对红土铁矿干燥焙烧条件进行研究.结果表明,在矿石粒度为0~3 mm且小于180目颗粒占25%,配焦粉量8%,焙烧温度850℃,焙烧时间90 min,干燥焙烧效果最佳.
The drying and roasting technology of the laterite ore raw was researched using thermogravimetric analysis（TG） and X-ray diffraction analysis（XRD） and other methods.The results are optimum under the condition that the granularity of the ore is 0~3 mm;the percentage of grain size（less than 180 mesh） is approximately 25%;the coke content is 8%;roasting remperature is 850 ℃ and roasting time is 90 minutes.
