Mineral Ores: The alluvial beach sand's main metal minerals are zirconium fluorite, rutile, ilmenite magnetite, and hematite; the main gangue minerals are quartz, feldspar, and mica. The mine adopts a strong magnetic-electric separation process because the magnetite has been removed during the gravity separation process, and the ilmenite has the strongest …

Gold Gravity Separation. The gravity separations are simple and separate mineral particles of different specific gravity. As the density of gold mineral is much bigger than gangue mineral, for the gold mine which has gold particles people often use the gravity separation process. Gravity concentration is a proven process for mineral beneficiation.
