3. Quartz sand magnetic separation process. The main purpose of magnetic separation of quartz sand is to remove iron impurities that dissociate from monomers in the process of rod grinding, such as weak magnetic minerals such as limonite, hematite, biotite, and tourmaline. The medium-strength magnetic separation process is often used.

Magnetic mineral inclusions in silicates are widespread in sediments as well as in igneous rocks. Because they are isolated from surrounding environment, they have potential to preserve original magnetic signature even in chemically altered sediments. Such inclusions may provide proxies to help differentiating the source of the host silicate. We measure magnetism …

Part of the quartz sand is not equipped with a magnetic separation process before acid leaching, so the quartz sand contains mechanical iron. After acid leaching, part of the mechanical iron remains in the quartz sand, and the mechanical iron is rapidly oxidized, contaminating the quartz sand, causing the quartz sand to directly turn yellow.
