| Abstract: |
| Tailing consolidation emission can reduce geological hazard and environmental contamination induced by tailing dam. Preparation of consolidation agent and dehydrating process selection are the key technologies. Based on multi-factors orthogonal test, reasonable component of consolidation agent applied to Xishimen iron ore is selected; armed with XRD,SEM, cementing performance and hydration products are researched to determine the substitutability to cement. Conducted with Three-phase industrial test, capacity of law about dehydration equipment is obtained. Disc vacuum filter which is adapt to 40%~45% underflow of thickener, has a high production and is not insensitive to concentration. Conducted with mercury injection test，micro-structure parameters，like the porosity and aperture,are measured to obtain the strength of test block indirectly. The value of strength is 0.78MPa which exceed the needed 0.5MPa. |
