我矿属伟晶岩矿床的钽铌矿,原矿经分级粗选所得的钽铌粗精矿所含的主要矿物为锰铌钽铁矿、锰钽矿、泡铋矿、钛铁矿、金红石、铌铁金红石、石榴石,以及少量的电气石、石英、云母、长石。建厂时,人为地在精选作业中加入磁铁矿作为钽铌矿物与石榴石分选介质。
Mine is a pegmatite deposit of tantalum and niobium ore, crude ore by roughing crude tantalum and niobium crude ore contained mainly manganese niobium tantalite, manganese tantalum, bismuth, ilmenite, rutile, Niobium iron rutile, garnet, and a small amount of tourmaline, quartz, mica, feldspar. When the plant was built, magnetite was artificially added to the selected job as the tantalum-niobium mineral and garnet separation medium.
