In quartz sand processing and sand washing plant quartz raw ore or quartz sand needs to be purified to remove impurities, such as iron, aluminum trioxide, mica,etc., so as to obtain high purity quartz sand. The SiO2 content of quartz sand after processing can reach 99.9% or higher, and the iron content should be reduced to 30 ppm or lower, so as to meet different industrial use. The quartz sand can also be processed into quartz powder through drying and grinding.


Technical process of high purity silica sand processing
The raw ore is crushed and screened to remove impurities, then washed and scrubbed by attrition scrubber to further remove the impurities from quartz sand. Then the symbiotic metal and non-metal impurities are removed by flotation machine or acid pickling machine and finally the high purity quartz sand is obtained by rinse.
Hengyang can provide a complete set of quartz sand processing and purification solution and equipmets. In addition to the conventional treatment process mentioned above, it can use particle size classification, strong magnetic separation, acid pickling and other technological processes according to the property of quartz sand to produce high-purity quartz sand products with different requirements.
