摘要
对云南兰坪天青石矿进行了重选试验研究,结果表明,采用单一摇床重选或采用螺旋溜槽分级-摇床重选均可获得合格的天青石精矿;天青石矿性脆易过磨,当粒度小于15μm,天青石矿物难以回收。工艺矿物学研究表明,部分微细粒的天青石矿物嵌布于方解石矿物中,细磨难以单体解离。
This paper makes experiment on gravity of the celestine ores in Lanping, Yunnan province. The results conducted by the author indicate we can gain the qualified concentrate of the celestine ores through the single shaking table test or the spiral classification - shaking table combined test. It also shows that it is hard to recovery when the size of the celestine ores are minus 15/rni because the ores are crisp and over grinding easily. The mineralogical investigations indicate that the partial celestine ores of very small particle size is embed in the cal-cite ores, and that it is hard to liberate when the celestine ores are fine grinding.
