ABSTRACT:
A method for economically manufacturing high-grade pellets for metallurgical use in a blast furnace from several grades of iron ores, which method can produce high-strength green pellets and save grinding cost by preferentially grinding only ores having a W.I. value not higher than 20 KWH/T, thus relatively easy to grind ores, and mixing the thus ground ores with ores which are hard to grind, in an agglomerating (lump-making) step, such as a pelletizing step.
