Quartz sand is a common non-metallic mineral resource. Its main component is SiO2. Generally, the main steps of refining quartz sand are as follows:
Mining: ore containing quartz sand is first collected from open pit or underground mines.
Crushing: Crush the large quartz sand of raw materials into small particles for subsequent processing.
Washing: Use water washing or chemical washing to remove non-metallic impurities such as soil and organic matter. Washing can be carried out using equipment such as sieving and washing machines.
Grinding: further grinding quartz sand to the required particle size.
Flotation: use chemical agents or gas bubbles to separate the metal impurities in quartz sand, so as to improve the purity and quality of quartz sand. Flotation can be carried out using equipment such as mechanical flotation or air flotation.
Sintering: quartz sand with high quality requirements also needs to be sintered. This step can make the quartz sand grains crystallize into more complete crystals at high temperature, thus improving the hardness and wear resistance of quartz sand.
Packaging: The quartz sand after the above treatment is packaged by packaging equipment, which is convenient for transportation and use.
It should be noted that the specific steps and methods of quartz sand refining may vary depending on the production process and equipment, and should be selected and optimized according to the actual situation.
