상동광산 광물찌꺼기의 비소제거를 위한 부유선별에서 인산염 첨가의 영향 = The Effect of Phosphate Addition in Flotation to Remove As in Tailings from Sangdong Mine

다국어 초록 (Multilingual Abstract)

Froth flotation was performed to study the effect of phosphate addition in the experiment to remove As from tailing of Sang-dong Mine. The experiment without Trisodium phosphate (T.S.P) showed that the removal rate of As was 88.7% and weight-ratio of floating material was 2.52%. By contrast, the experiment with T.S.P showed that the removal rate of As was 92.74% and weight-ratio of floating material was 2.26%. In flotation without T.S.P, the average particle size of float material was 19.34 um and the amount less than 10um was 40.2%. On the other hand, in flotation with T.S.P the average particle size of float material was 176.8 um and the amount less than 10um was 6.5%. The result of X.R.F analysis presented that contents of $SiO_2$ was 42.74% in float material of the experiment without T.S.P. In contrast, contents of $SiO_2$ was 29.56% in float material of the experiment with T.S.P.
