Development of high extraction magnetic filtration by the kaolin industry of Georgia

An entirely new level of magnetic filtration technology was put into full commercial production by the kaolin industry of Georgia, U.S.A. during 1973 - 1975. At present, five kaolin producers in Georgia are operating large magnetic filters each capable of producing over 4000 liters of kaolin slurry per minute or over 60 tons of kaolin per hour on a dry basis. When operated at the 4000 liters per minute rate, these five large magnetic filters have a combined capacity approximating the entire waterwashed coating and filler kaolin produced in the U.S.
