滑石微粉提纯的技术研究

Research on the technology of purification of talc

天然滑石矿是多种矿物的集合体。原矿石可采用人工选矿进行提纯,但对于微粉颗粒人工选矿是无能为力的。利用滑石与伴生矿物杂质的物理性质的差异以及其在超细粉碎过程中不同的运动特性达到提纯的目的。得到的滑石,纯度明显提高,粒径分布窄,适宜作高档功能性粉体。

Natural tale is a multimineral aggregate. Usually, the purification of tale is to be milled after the manual dressing of original mine. However,the manual dressing is uneffectual for uhrafine particles. By means of the differences of physical property and motion characteristics in the superfine pulverization between talc and associated minerals, the purification of talc can be achieved. The talc obtained has high purity and narrow size distribution,it is suitable used for the high - functional powder.
