EXPERIMENTAL STUDY OF SOLIDIFICATION TECHNOLOGY OF THE BAUXITE MINE SLIME

Traditional disposal of the high water content slime from the beneficiating and washing of the bauxite mine takes a long time to consolidate and causes environment contamination.Experimental results presented in this paper show that compound curing agent made up of 72% cement,20% gypsum,5% lime and 3% sodium sulfate or made up of 72% lime,20% gypsum,5% flyash and 3% sodium sulfate could improve solidification intensity and durability if they were used at a ratio of 1:10(curing agent : slime).Its low cost and environment-friendly merits create a great potential for future application.
