PURPOSE: Provided is a method for preparing zeolite germanium mineral by using a reduction calcination to completely remove harmful components from the zeolite and keep various minerals helpful to a human body such as germanium, calcium, magnesium, sodium and the like. CONSTITUTION: The method comprises steps of: (i) putting gathered zeolite containing germanium in calciner and heating the calciner to gradually increase the temperature of the inside; (ii) gradually opening the door of the calciner according to the temperature increase to supply oxygen thereto; (iii) completely opening the door of the calciner when the temperature of the calciner becomes 800-1,000 deg.C; and (iv) when the reduction calcination is complete, stopping heating and naturally cooling down the temperature of the calciner.
