DEPURATOR PREPARED USING NATURAL MINERAL POWDER CONTAINING GERMANIUM AND METHOD FOR PREPARING THE SAME BY PREPARING NATURAL MINERAL POWDER, PREPARING QUICKLIME, MIXING NATURAL MINERAL POWDER AND QUICKLIME AND AGING MIXTURE

PURPOSE: To provide a depurator capable of obtaining more improved depuration capability using an existing depuration facility by adding natural mineral powder containing germanium to a depurator in a certain ratio, and a method for preparing depurator using natural mineral powder containing germanium. CONSTITUTION: A depurator using natural mineral powder containing germanium comprises mineral powder containing 65 to 75 wt.% of natural germanium having a moisture content of 16 to 18%; and 25 to 35 wt.% of quicklime, wherein the natural germanium mineral powder additionally includes certain quantities of sericite, zeolite, biotite, calcium oxide, magnesium oxide and alkali constituents, and wherein the quicklime contains 85 to 95 wt.% of calcium oxide and 93 to 97 wt.% of alkali constituents. A method for preparing depurator using natural mineral powder containing germanium comprises: a natural mineral powder preparation step of mixing natural germanium mineral powder having a moisture content of 16 to 18% with zirconium oxide, sericite, zeolite and biotite; a quicklime preparation step of mixing 85 to 95 wt.% of calcium oxide and 93 to 97 wt.% of alkali constituent with quicklime; a mixing step of blending 65 to 75 wt.% of natural mineral powder with 25 to 35 wt.% of quicklime; and an aging step of agitating mixed powder supplied from the mixing step in an agitator until an exothermic temperature of the mixed powder is not increased any more.
