The Owner first wants to see if the quartz ore can be used to make HPQ sand, which is very rare and needed in high-end industry. However, since it is not qualified to make HPQ sand, so Prominer helps him to build the plant to produce quartz sand and powder for quartz slab industry. Compared to mineral beneficiation process, the plant is not very complicated but mainly crushing, grinding and screening. The main concern for such plant is to reduce the iron impurities and other particles with contamination. So optical sorting is used to remove the contaminated material, and the grinding ball mill adopts ceramic liners and the grinding media is ceramic balls. Before final product packing, it is processed by the magnetic separator to reduce the iron inside.
