THE FIELD SOLIDITY TREATMENT SYSTEM FOR MINE TAILINGS

摘要

PURPOSE: A field hardening treatment method of a mineral residue is provided to prevent the rainwater infiltration by the torrential rain, and the scattering of the mineral residue formed in a micro particle. CONSTITUTION: A field hardening treatment method of a mineral residue comprises the following steps: mixing the mineral residue including over 50wt% of pozzolan reaction material with the size of 0.075~4.75 millimeters containing silica and alumina, with 20~30wt% of calcium hydroxide; burying the mixture to a mineral residue storing yard; and inducing a pozzolanic reaction to the mixture for hardening the mineral residue.
