云南变质类型石英岩提纯工艺试验研究

Experimental Study on Purifi cation of Metamorphic Quartzite from Yunnan Province

云南省的硅石资源非常丰富,分布极其广泛且种类较多,选用变质类型石英岩,并根据其杂质性质进行提纯试验研究。变质类型石英岩在粉碎至-500目,四酸联浸24h提纯条件下,最终可得到石英精矿杂质总量为93.7g/t的高纯石英。

The silica resource in Yunnan province is very rich and its distribution is extremely broad.In this experiment the metamorphic quartzite was purifi ed under these conditions as the following ： the samples were crushed to-500 mesh and soaked in four kinds of acids for 24h,a high purity quartz concentrate only with 93.7 g/t of impurities was obtained f inally.
