    Importance of fine ore chemical composition and high

    Abstract In the iron ore industry significant emphasis is placed throughout the mining process on meeting chemical composition specifications for the export of fine ores. However, little has been published on the implications of ore chemical composition for iron ore sinter and pellet product quality. The ore bulk composition and the nature of the minerals in the fine ore both play a critical
