The processing technology for enriching silica and removing iron was directly worked out based on analysis of a Kazakhstan quartz sand mine . Results show that after beneficiation the quartz sand can be upgraded to concentrated one as stated in building materials industrial standard of People's republic of China "siliceous materials for plate glass making". At the same time this technological data can provide reference for mining design.%通过对哈萨克斯坦某矿石英砂的性质分析，针对性地拟定了除铁提硅的选矿工艺。试验研究表明，该石英砂经选别后可以获得中华人民共和国建材行业标准《平板玻璃用硅质原料》I类一级品（或I类优等品）精矿。同时，为哈方提供矿山设计依据。
