The Wet Drum Magnetic Separators from Serpent & Dove are typically used in coal and iron ore applications. Heavy media processes often utilise materials such as finely ground magnetite or ferrosilicon to adjust the density of the water and separate products that sink from products that float. Losses occur when distinct media particles cling to either the floating or sinking products, and can be minimised with the use of Serpent & Dove’s wet drum magnetic seperators.
The floating and sinking products are passed over drain and rinse screens to rinse off clinging media particles. The resulting slurry is then passed through the wet drum magnetic separator to recover a large amount (> 99.9% in many cases) of the magnetite or ferrosilicon particles to be re-introduced into the heavy media bath.
