江西省兴国县风化残积型高岭土矿是—中大型砂性高岭土矿床。矿石矿物有高岭石、白云母、长石、石英,原矿所含铁主要赋存于硅酸盐矿物中,经选矿除去。矿石先经碎散(擦洗)、筛分再经旋流器分选提高精矿Al_2O_3含量和产品细度,可获造纸填料级高岭土精矿、瓷土精矿,而对+0.074毫米尾矿,通过磁选—浮选,可获白云母精矿、陶瓷级长石精矿以及平板玻璃原料用石英精矿。通过试验研究,矿石量的87.3%得到利用,经济效果较好。
Xingguo County, Jiangxi Province weathered residual type kaolin mine is - large sandstone kaolin deposits. Ore minerals are kaolinite, muscovite, feldspar, quartz, iron contained in the ore mainly occurs in silicate minerals, removed by beneficiation. Ore first by the broken (scrubbing), screening and then by the cyclone sorting improve the concentrate Al_2O_3 content and product fineness, can be made of paper-filler grade kaolin concentrates, porcelain concentrate, and +0.074 mm tailings, through Magnetic separation - flotation, available muscovite concentrate, ceramic grade feldspar concentrate and quartz glass concentrate for plate glass. Through experimental research, 87.3% of the ore amount is utilized, and the economic effect is better.
