一、原料性质 将石城钽铌矿的原矿磨至1毫米以下,然后分级并分别用摇床粗选,所得粗精矿中含有钽铌铁矿、细晶石、锰钽矿、钛钽铌矿、钽铌锡石、锰钽铌铁矿、磁铁矿、赤铁矿、褐铁矿、泡铋矿、锆英石、电气石及少量石英、长石等。粗精矿再用弱磁场磁选机除去磁铁矿,用摇床排电气石、石英和长石,最后用中等场强的磁选机除去亦铁矿、褐铁矿,获得含钽铌铁矿、锰钽矿、钛钽铌矿、锰钽铌铁矿等具有中等磁性的钽铌矿物
First, the nature of the raw material Shicheng tantalum and niobium ore mill to 1 millimeter below, and then grading and were shaker rougher, the resulting crude concentrate containing tantalum niobium iron ore, fine spar, manganese tantalum ore, titanium tantalum and niobium ore , Tantalum and niobium cassiterite, manganese tantalum and niobium iron ore, magnetite, hematite, limonite, bismuthinite, zircon, tourmaline and a small amount of quartz, feldspar and so on. Coarse ore and then weak magnetic field magnetic separator to remove magnetite, with shaker discharge tourmaline, quartz and feldspar, and finally with a medium field strength magnetic separator also remove iron ore, limonite, obtained with tantalum niobium iron Minerals, manganese tantalum ore, titanium tantalum niobium ore, manganese tantalum niobium iron ore with medium magnetic tantalum and niobium minerals
