Each one a piece of the puzzle. The practical application of the new magnetic separation method should indicate within what time frame the new method can be introduced. Van Silfhout points out that the research published in The Journal of Physical Chemistry Letters (Colloidal stability of aqeous ferrofluids) is 'just' one piece of the puzzle.

Natural kaolin has color as mined due to the iron containing micas, tourmaline, pyrite, anatase and rutile present in the material. To remove these impurities, kaolin can be magnetically cleaned with a continuous high gradient magnetic separator to produce highly white material suitable for paper or porcelain (Oder and Price, 1973; …

A magnetic separation system designed to hold and separate to the side of the tubes magnetic particles in 12 X 75 mm tubes. The two-piece system consists of a test tube rack, which fits over a magnetic separation rack containing rare earth magnets. The two-piece design allows test tubes to be set up, incubated and magnetically separated
