Silica sand processing plant remove the impurities such as iron, aluminum trioxide, mica etc through crushing, scrubbing, washing, classifying and beneficiation.
Quartz raw ore or quartz/silica sand needs to be purified to remove impurities so as to obtain high purity silica sand. The SiO2 content of slicasand 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.
The high-end glass sand processing plant, located in southwest China, produces silica sand for high-end glass. Through repeated experiments and finally by scrubbing and flotation process, the final high purity silica sand with iron content below 80ppm is obtained. The floatation equipments and scrubbing machines used in the production line is made of high quality stainless steel to avoid secondary iron pollution to silica sand. A new type of reagent developed by advanced technology has a good effect in removing impurity by flotation.
