  • Strategy for efficient utilisation of low grade iron ores

    Magnetite concentrate is typically high in Fe grade and releases heat when oxidised. Hence it is an ideal sweetener to maintain sinter grade and quality when high proportions of low grade ores are used in the blends. However often magnetite concentrate is very fine and more costly. It is therefore important to develop strategies for its effective utilisation to improve the sinter quality while
