Extraction of minerals in deionized water and elimination effect of heavy metals in water by Nohwado Quartz Porphyry were examined. When the Nohwado Quartz Porphyry was immersed and stirred in deionized water at 0.5, 1.0, 1.5 and 2.0% concentration for 3 hours, various minerals concentration of the all stirred water were suitable for potable water. Particularly, when the lead, copper, cadmium and arsenic solution were shaked with Quartz Porphyry at <TEX>$20^{\circ}C$</TEX> for 24 hours, the elimination rate of each mineral was 99.5, 99.9, 95.0 and 66.5%, respectively.
