High purity quartz sand is a kind of high purity colorless, transparent and uniform grain quartz sand, which is mainly used in semiconductor, optics, electronics, optical fiber and other high-tech fields. The production process generally includes the following steps:
Raw material processing: select high-purity natural quartz sand or artificial quartz, and process it through crushing, screening, etc. to make it meet certain particle size requirements.
Cleaning: the screened quartz sand is cleaned to remove impurities and oxides attached to the surface and improve the purity of quartz sand.
Leaching: put the cleaned quartz sand into the acid solution for leaching to remove the residual iron, aluminum and other impurities, and change the chemical properties of the quartz surface to improve the flotation efficiency.
Flotation: add foaming agent and collector to the leached quartz sand for flotation separation to improve the purity and particle size of quartz sand.
Drying: drying the flotation high-purity quartz sand to remove water on its surface and make its particles more uniform.
Particle size screening: screen the dried high-purity quartz sand to obtain quartz sand products that meet customer requirements.
Packaging: package the high-purity quartz sand whose particle size meets the requirements, conduct quality inspection, and finally deliver it to the customer.
It should be noted that the production process of high-purity quartz sand should be carried out in a dust-free and pollution-free environment to avoid affecting the purity of quartz sand products. At the same time, it is necessary to pay attention to safety measures during the operation process to avoid harm to personnel and equipment.
