前言试验根据76年5月包钢革综字第126号下达:“用选矿厂 TR_2O_3为25%的稀土粗精矿作为原料进行精选,要求稀土精矿品位 TR_2O_3≥60%回收率>50%”。文中并明确指出获得高品位稀土精矿对于“满足当前湿法冶炼的急需,具有重大的现实意义”,同时规定“该项任务由冶金研究所、有色三厂负责,选矿厂参加。5月份在有色三厂进行小型试验,6月份对小型试验结果进行审定”。试验在三厂党委领导下,以选冶车间为基点,由有色三厂、冶金
Preface According to the trial of Baogang Shijie, No. 126, issued in May 2006: “The rare earth concentrate with TR_2O_3 concentration of concentrator is selected as the raw material, and the recovery rate of TR_2O_3≥60% of rare earth concentrate is required to be> 50% ”. In the article and clearly pointed out that the access to high-grade rare earth concentrate for “the urgent need to meet the current wet-smelting, with great practical significance,” while the provisions of “the task by the Institute of Metallurgy, Nonferrous three plants responsible for dressing plant to participate in May Non-ferrous three small-scale test, small test results in June validation. ” Test under the leadership of the three plant party committees, dressing and smelting workshop as the starting point, from the non-ferrous three plants, metallurgy
