Abstract: Through laboratory analysis test, We can study that Pingguo Bauxite Mine Slime with high water content, small particles, the big specific surface area, PH was neutral, and other characteristics that can be seen as an approximation of the colloid. Through the slime electrophoresis settlement with the static test for the settlement, Note settlement electrophoresis can be used to reduce the direct discharge of sludge water content, improve concentration, put slime as the mined-out areas of reclaimed soil.
