Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that these examples are only for illustration of the present invention, but not to limit the scope of the present invention in any way.
[0017] In this embodiment, the vein quartz produced in Donghai County, Jiangsu Province is used as raw material, and processed according to the following procedures:
[0018] 1. Crush the vein quartz with a hammer crusher or jaw crusher to 4-25mm, and remove the clay impurities attached to the surface of the quartz minerals by washing and grading desliming methods; after the deslimed vein quartz minerals are dried, , sort and discard the non-quartz impurities that can be identified by naked eyes.
[0019] 2. Electrostatic removal of impurities is carried out on the sorted quartz ore. The drum speed of the electrostatic removal equipment is 100r / min, the voltage is 18,000 volts, and the electrostatic remov...
