阿太尔某钽铌矿属伟晶岩矿床。66年曾做过重选试验,77年又做了工业性试验,都取得了一定的选别指标。随着选矿设备的发展,今年对该钽铌矿石进行了强磁选别的试验研究,本文叙述了对该矿石的试验研究情况,井对今后的选别工艺进行一些讨论。一、矿床地质及矿物该矿主要属伟晶岩矿床,可分为中粗粒黑云母和片麻化细粒云母伟晶花岗岩两种。均属海西宁期形成。构造节理发育完全,节理面平直光滑。矿脉成似扳状体,不具明显分带性,但大体可归纳为:中粗粒伟晶岩;石英——钠长石——锂辉石带;小块体伟晶岩带;石英——钠长石交代集合体;糖晶状钠长石交代集合体。
Artest a tantalum niobium mineral pegmatite deposit. 66 years have done re-election test, 77 years has done an industrial test, have made a certain selection index. With the development of mineral processing equipment, the tantalum-niobium ore has been magnetically selected for testing this year. This paper describes the experimental research on this ore and some discussions on future sorting techniques. First, the deposit geology and mineral The mine is mainly pegmatite deposit can be divided into two kinds of coarse-grained biotite mica and grained mica gravel. Are formed during the Hercynian period. Structure joints developed completely, the joints smooth and straight surface. The veins are similar to pull-shaped bodies, and have no obvious zonation, but can be generally summarized as: medium-coarse pegmatite; quartz-albite-spodumene zone; small pegmatite zone; quartz- Albite metamorphosed aggregates; sugar crystal albite metamorphosed assemblages.
