一、前言江西某地石墨矿属区域变质形成的小鳞片状晶质石墨矿床,该矿除回收石墨外还可以综合回收含钒白云母和石英砂,是我国第一个石墨矿石中伴生含钒白云母的石墨矿床。我所于1979年对该矿区的含钒白云母石墨片岩矿样、石英石墨片岩矿样和混合石墨矿样进行了综合回收的研究。含钒白云母与石墨伴生,钒以类质同象赋存于白云母中。本文着重介绍混合矿样的研究情况,其混合矿样的石墨品位为8.88％,五氧化二钒的品位为0.312％,石英的含量为72.78％。根据原矿性质的考察,制定了用浮选的方法先回收石墨,然后将石墨尾矿进行脱泥,所得的泥、砂,再用胺类作捕收剂来回收含钒白云母,用此流程处理后最终精矿达到下列指标:石墨精矿品位为92.25％,回收率为95.66％;含
I. Preface The small scale flaky crystalline graphite deposit formed by the regional metamorphism of graphite deposits in a certain area of Jiangxi Province can be recovered synthetically from vanadium-bearing muscovite and quartz sand. It is the first graphite ore associated with vanadium Muscovite graphite deposit. In 1979, I conducted a comprehensive study of vanadium-bearing muscovite graphite schist mineral samples, quartz graphite schist mineral samples and mixed graphite mineral samples in this mining area. Vanadium-containing muscovite is associated with graphite and vanadium is present in muscovite in the same way. This article focuses on the study of mixed mineral samples, the mixed sample of graphite grade 8.88%, grade of vanadium pentoxide is 0.312%, quartz content of 72.78%. According to the investigation of the nature of the ore, developed by the flotation method to recover graphite, and then the graphite tailings desliming, the resulting mud, sand, amine and then used as collectors to recover vanadium-containing muscovite, with this process After treatment, the final concentrate reaches the following indexes: the grade of graphite concentrate is 92.25% and the recovery rate is 95.66%; with
