Usually, strong magnetic separation equipment is used to remove these impurities.Silica sand is commonly used in the foundry industry. With a high melting point of 160 C, the silica sand is normally sintered in a high temperature furnace. However, silica with contents of calcium, aluminium, magnesium, and chlorine, etc. can form low melting point eutectics. Therefore, a relatively low power laser can be used to sinter the silica sand directly.
