阴/阳离子捕收剂反浮选制备高纯石英砂研究

Study on Preparing Super Quartz Sand by Cationic/anionic Collector Reverse Flotation

对含长石、云母等粘土矿物的石英岩 ,经粉碎、磨矿、摇床选别后 ,采用阴 /阳离子捕收剂反浮选 ,可制备SiO2 含量达 99 97%的高纯石英砂。

Super quartz sand containing SiO 2 as high as 99.97% can be prepared by cationic/anionic collector reverse flotation from quartzite containing clay minerals such as feldspar and mica after crushing, grinding and tabling. This technology can also effectively remove heary metal and secondary iron minerals.
