The process of magnetic separation was in use as long ago as the end of the last century for separating substances differing from one another in their magnetic power. At that time, this process was used particularly in the dressing of ores, particularly iron ores. Recently, magnetic separation has also been used for the purification of kaolins (German Offenlegungsschrifts Nos. 2,420,436 and 2,534,044), the iron
