摘　　要：本文选取江苏某地低品位天然河（湖）砂为研究对象，经过擦洗-脱泥-重选-磁选-擦洗-浮选-深度提纯的工艺流程处理后，获得的石英精砂SiO2含量提高至99．62％，Fe2O3含量降至52ppm，可满足超白玻璃用硅质原料的要求；获得的钾长石中K2O〉9．0，Na2O〈3．0，K2O＋Na2O〉11．0，可满足优质玻璃及陶瓷釉料用钾长石的需求。In this paper, we select low grade river and land sand of Jiangsu as the research object. After the technology process of ＂ scrubbing - desliming - gravity separation - magnetic separation - scrubbing - flotation - depth purification＂, in the final concentrate sand the content of SiO2 increases to 99. 62% and that of Fe203 reduces to 52ppm, meeting the re- quirements on siliceous materials of ultra white glass; while in the final potassium feldspar the content of K2O〉 9.0, Na2O 〈3.0 and K2O ＋ Na2O〉 11.0, meeting the requirements on potassium feldspar for high quality glass and ＂ceramic glaze.
