A cured / manganese slag processing method of high concentration water-soluble manganese stabilized

The present invention discloses a method of solidification / stabilization process manganese slag high concentration water-soluble manganese, the method comprising the steps of: (1) the activated silica dispersion with water to form a mixture; (2) the above mixture manganese slag was added and stirred for 1-3 min; (3) magnesium oxide was added, and stirred for 30-40 min; (4) aged 7 to 14 days. Wherein the amount of active silica is from 1% to 5% by weight of manganese slag. The present invention provides a cured / method of stabilizing high concentrations of water-soluble manganese slag processing can be reduced while the concentration of the leaching of manganese, but the manganese slag after treatment pH is maintained within the range 6-9.
