红土型镍矿焙烧工艺中试研究

RESEARCH ON PILOT SCALE EXPERIMENT FOR NICKEL LATERITE CALCINING PROCESS

对红土型镍矿在生产镍铁的RKEF法工艺过程中的还原焙烧环节进行了中试研究。试验中,主要分析了元素分布与粒级的关系、焙烧温度的选择、还原剂的配比,也讨论了焙烧生产中的设备及其相关操作参数。

The pilot scale experiment of laterite calcining in the RKEF process was studied.The relationship between elements distribution and grades,calcining temperature,ratio of reductants and some operation parameters were also analyzed.
