Quartz Impurities Removal Process and Equipment

2020-11-13  Magnetic separation is one of the effective methods to remove iron-containing impurities in raw materials. Since the minerals such as hematite, limonite and biotite contained in the raw materials have weak magnetic properties, they can be selected when the magnetic field strength is above 8×105A/m (ampere/m) by using a wet-type strong magnetic separator.
