且干布拉克磷灰石矿床产于晚远古代超基性杂岩体中,品位低,磷灰石岩矿以透辉石型磷灰石为主。该矿石经实验室试验和扩大试验,采用浮选—重选联合流程,最终获得了优质磷精矿,同时也获得了透辉石精矿和蛭石精矿,基本上实现了无尾矿工艺,综合回收了有用矿物资源,提高了矿床的经济效益。 一、矿石性质 1.矿石类型及结构构造 矿石的类型主要是浸染状,其次为团块状、细脉状磷灰石。主要矿物有透辉石、纤闪石、蛭石、磷灰石、磁铁矿、榍石等。
And dry Brak apatite deposits produced in late ancient ultrabasic complex body, low grade, apatite rock mainly diopside apatite. The ore by laboratory tests and expand the test, the flotation - re-election joint process, and ultimately obtained high-quality phosphate concentrate, but also obtained diopside concentrate and vermiculite concentrate, basically achieved without tailings technology , A comprehensive recovery of useful mineral resources, improve the economic benefits of the deposit. First, the nature of the ore 1. Ore types and structure of the structure of the ore type is mainly disseminated, followed by the massive, fine vein apatite. The main minerals are diopside, amphibole, vermiculite, apatite, magnetite, stone and so on.
