各类含磷矿石在矿物和化学成分上都是综合性的,而磷灰石-霞石矿石在含磷组份的赋存上和数量上则是独立的。这种类型矿石的主要造岩矿物是磷灰石、霞石、霓透辉石;其次为榍石、钛磁铁矿、长石;次要矿物是异性石、三斜闪石、绿层硅铈钛矿。按矿物成分的数量,划分为磷灰石-霞石、霞石-磷灰石、榍石-磷灰石矿石。主要组份(磷)与一种矿物(磷
Various types of phosphorus-bearing ores are synthetic in both mineral and chemical composition, while apatite-nepheline ores are independent of the abundance and abundance of phosphorus-containing components. The main rock-forming minerals of this type of ore are apatite, nepheline, and neondixene; followed by cristobalite, titanomagnetite and feldspar; and the secondary minerals are heterosexual, tridrianite, Cerium. According to the quantity of mineral components, it is divided into apatite - nepheline, nepheline - apatite, gallstone - apatite ore. The main component (phosphorus) and a mineral (phosphorus
