前言含锂铍花岗伟晶岩中,有用矿物之间,有用矿物和脉石矿物之间,可浮性差异甚小。随它们的成矿条件和浮选前矿石的准备情况不同或浮选水质的差别,各矿物的可浮性在颇大的范围內变动。近年来,我们用丹宁(或烤胶)抑制绿柱石,用氧化石腊皂、异羟肟酸分別做锂辉石和绿柱石的扑收剂,优先浮选锂辉石的全优浮选方案,经过反复试验,结果表明,该方案对伟晶岩脉中锂矿石和铍矿石的分选均适合。全流程的关键是优选锂时尽可能将大部分锂辉石和部分“重矿物”浮出,为得到高品位的铍精矿做准备。全流程主要分为抑铍优选锂和解吸抑 Preface The lithium-bearing beryllium granite pegmatite, useful minerals, useful minerals and gangue minerals, floatability difference is minimal. With their different metallogenic conditions and pre-flotation ore preparation or flotation water quality differences, the flotability of minerals in a wide range of changes. In recent years, we use tannin (or baked plastic) to inhibit the beryl, with soap stone oxide, hydroxamic acid spodumene and beryl respectively, the preferred flotation spodumene flotation program After repeated tests, the results show that this scheme is suitable for the sorting of lithium ore and beryllium ore in pegmatite vein. The key to the whole process is to optimize the lithium as much as possible, most of the spodumene and part of the “heavy minerals” surfaced, in order to obtain high grade beryllium concentrate preparation. The whole process is mainly divided into beryllium preferred lithium and desorption
