| Abstract: | By using the method of sample-disttlrbing thick liquid-dispersion-subsidence classification to process the low grade diatomite of Shuangiiang, Yunllan the diatomit4 concentratesand middlings which content SiOZ 82.24%, Al,O, 6.9%, FeZO3 l.04% and SiO, 76.18%,Al,O, 10.10%, Fe,O3 l.46%,of which production value are 3.29% and 14.56%, respectivelycan be get. By using the hydrochloric acid to immerse the diatomite concentrates and toclean, SiO, increases to 84.36% and the contents of A12O3 and FeZO3 are 7.53% and 0.80%respectively. By tising the hydrochloric acid to immerse and bake the diatomite middlings, tilecontents of SiO2, Al,O, and FeZO3 are 83.92%, 11.32% and 1.10%, SiO, is lllorethan 80% ill above two samples which underwent the hydrochloric acid immersion orhydrochloric acid immersion and roasting. They meet the need to product diatomite filter aid. |
