摘要:深入研究了卢氏锂辉石ー锂云母型稀有多金属矿石的工艺矿物学特征,为矿石选治工艺提供理论基
础和科学依据。查明了矿石中锂辉石、锂云母、绿柱石、铌钜铁矿、锑钼矿、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%。铌佃矿物与锂云母和钾电气石关
系密切,伽无独立矿物、载体矿物为长石和锂云母。锂辉石和锂云母粒度较粗,倪钮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品簇状集合体分布于粒间隙及微裂隙中。

Abstract This paper thoroughly studied the processing mineralogy features of Spodumene-lepido
lite 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
recovered and utilized
rtz and feldspar can also be comprehensively recovered in this ore. Use-
ful minerals accounted for 94. 3% in the ore. Niobo-tantalic minerals were closely related to le
pidolite 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
