Abstract

PURPOSE: To recover Na component in the desulfurized slag generated at the desulfurization treatment of the molten pig iron with the desulfurizing agent consisting of Na2CO3 as the main component as water glass, by extracting soluble Na2O.nSiO2, etc. by peforming the leaching treatment for the above desulfurized slag with water.
CONSTITUTION: The desulfurized slag which has been generated by performing the desulfurization treatment of the molten pig iron with the desulfurizing agent consisting of Na2CO3 as the main component and has been pulverized to a grain size below 20mm, is fed to the water tank 4 from the hopper 1 through the conveyor 3. In this tank, the desulfurized slag is leached with the amount of water (giving a temperature below 60°C) of the weight ratio of water/desulfurized slag more than 1, and the soluble substance such as Na2SiO3, etc. is eluted. Then, the recovered liquid containing the coluble substance such as Na2SiO3, etc. is recovered to the vessel 15 and the residuum is recovered to the vessel 13 respectively.
