摘　　要：深入研究了卢氏锂辉石-锂云母型稀有多金属矿石的工艺矿物学特征,为矿石选冶工艺提供理论基础和科学依据。查明了矿石中锂辉石、锂云母、绿柱石、铌钽铁矿、锑钽矿、细晶石和铯榴石等稀有金属矿物可供回收利用,石英和长石亦可综合回收,有用矿物占矿物量的94.3%。铌钽矿物与锂云母和锂电气石关系密切,铷无独立矿物、载体矿物为长石和锂云母。锂辉石和锂云母粒度较粗,铌钽铁矿和绿柱石粒度细小。铌钽铁矿主要呈粒柱状、绿柱石主要呈柱状和晶簇状集合体分布于粒间隙及微裂隙中。This paper thoroughly studied the processing mineralogy features of Spodumene- Lepidolite pattern rare polymetallic ore,which could supply theoretical base and scientific evidence for mineral separation and metallurgy technology. It was found out that rare metal minerals including spodumene,lepidolite,beryl,columbite- tantalite,stibiotantalite,microlite and pollucite can be recovered and utilized,quartz and feldspar can also be comprehensively recovered in this ore. Useful minerals accounted for 94. 3% in the ore. Niobo- tantalic minerals were closely related to lepidolite and elbaite,there was no independent mineral of rubidium,which hosted in feldspar and lepidolite. Spodumene and lepidolite had comparatively rough granularity,columbite- tantalite and beryl had smaller particle size. Columbite- tantalite mainly presented grain and columnar,beryl mainly presented columnar and drusy- aggregate and distributed in intergranular and micro cracks.
