PROBLEM TO BE SOLVED: To improve a refining and processing method for rocks which belong to conventional quartz porphyry and for granite porphyry. SOLUTION: A refining and processing method for oolite and a method for utilizing the purified material are provided. The refining and processing method for granite porphyry comprises a first processing process where granite porphyry, which is buried in the mountains of Gifu and has chemical composition consisting of anhydrous silicon (SiO2), aluminum oxide (AI2O3), ferric oxide (Fe2O3), ferrous oxide (FeO), magnesium oxide (MgO), calcium oxide (CaO), sodium oxide (Na2O), potassium oxide (K2O), titanium oxide (TiO2), phosphoric acid anhydride (P2O5), manganese oxide (MnO), and free water, is used as a main raw material, and the oolite is mined from a vein layer, in which the oolite is deposited, crushed to small particles or coarse sand-like crude ore and dried naturally, a second processing process where the oolite raw material in the crude ore state is hot-air dired at about 120 to 450 deg.C to be pulverized, and a third processing process where the pulverized oolite raw material is further classified with air to obtain the refined particles having particle diameters of about 0.10 to 50.00 μm. |
