Use of a magnet on each size-classification of concentrates can be very helpful to remove those impurities which are magnetic. Some prefer to use a fine painter's brush to separate out the non-magnetic impurities. Separation can also be accomplished by using your fingers. This step goes faster if you only do small amounts of concentrate at a time.
