Abstract
According to the element analysis of Korean Quartz Porphyry, the ignition loss related to porosity was 7.03, 3.36, 2.09 and 0.73% in the order of Suanbo, Yeachen, Angang and Kyongsan. Extraction of minerals in deionized water and elimination effect of heavy metals in water by Quartz Porphyry were examined. When the Quartz Porphyry of the Suanbo, Yeachen of 0.5~2.0% concentration and the Quartz Porphyry of the Angang of 1.5% concentration were immersed and stirred in deionized water for 3 hours at 180rpm, various minerals concentration of the all stirred water were suitable for potable water. But Quartz Porphyry of the Yeachen was not suitable for potable water because of excess extraction of iron. The elimination rate of lead in single solution was 99% by Quartz Porphyry of the Suanbo, Yeachen and Angang of 3% concentration, Cadmium by Quartz Porphyry of the Suanbo of 7% concentration was eliminated about 98% in 1 hour. The copper was significantly eliminated in Quartz Porphyry of low concentration. Especially in Quartz Porphyry of Angang at 0.4% concentration, the rate of ion exchange was 99% in 4 hours. But elimination effect of arsenic in water by Korean Quartz Porphyry was very low.
