Experimental study on material composition and concentration of a low grade diatomite ore in Jilin shows that the ore is mainly composed of opal and its variants and a small amount of quartz, feldspar, kaolinite and other impurities mineral. The best scrub and acid leach conditions is determined by the experiments;Finally using the method of scrub-Classiifcation of settlement-acid leach process, a high quality diatomite which contents SiO2 82.45%, Fe2O3 0.72%is gained successfully.
