METHOD FOR PRODUCING IRON ORE AGGLOMERATE USING WASTE SOLUTION AFTER WATER IMMERSING TREATMENT OF Na- CONTAINING SLAG

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an iron ore agglomerate enabling the inexpensive treatment of a large quantity of Na-containing waste solution generated by water immersing treatment and water vapor aging treatment of Na-containing slag and also capable of attaining the improvement of the yield of a product agglomerate and the increase of the production. ;SOLUTION: When adding a blending water to pulverized iron ore, conducting granulation, successively conducting each treatment of drying, water removing and preheating and moreover conducting firing to form into a fired pellet, as the blending water, a waste solution after the water immersing treatment and/or water vapor aging treatment of Na-containing slag is used.;COPYRIGHT: (C)2001,JPO
