A Suitable Processing Method for Quartz Mines in Sri Lanka

High purity quartz important to produce fused quartz and Silicon, which are used in computer chips and other electronic devices. Other than that there is a demand for high purity silica powders of sub-micron size in various industries. Grinding of quartz is comparatively difficult because of its high hardness (Moh’s scale hardness is 7).The process is commonly used in the production of high-purity quartz for use in various industries, such as electronics, optics, and solar energy. The process typically involves the following steps: Crushing and grinding: The quartz ore or concentrate is first crushed and ground to reduce the particle size and increase the surface area for acidUnderstanding the Process of Quartz Mining and Processing
