摘要
根据福建东山县硅砂矿的矿石性质和生产现状，进行了多方案的除铁降杂试验，确定了以塔式螺旋溜槽为主体设备的单一重选除铁降杂工艺流程．该工艺流程简单，可使硅砂精矿中的 Ｆｅ２Ｏ３含量降至 ０．１％以下，效果显著，选矿成本低廉，特别适用于提高硅砂矿的产品质量．
Based on the deferrization and decontamination test by several schemes on silica sand in Dongshan county of Fujian Province in the light of its characteristics and the produc- tion fact there, a single gravimetric concentration process is decided, with a tower-type spi- ral chute as main equipment. The proposed process is simple in its flowsheet, by which Fe2O3 content in the silica sand concentrate can be reduced to lower than 0.1 %, achieving re- markable results with a lower processing cost. It is especially suitable for upgrading the quality of silica sand products.
