Application of Rapid X-Ray Diffraction (Xrd) and Cluster ...

2012-3-20  Abstract. Traditionally, grade control of iron ores has relied on elemental analysis of sampled materials such as blast cone drill cuttings. This analysis provides a standard elemental suite (Fe, SiO 2, Al 2 O 3, P, Mn, S, MgO, CaO and TiO 2 along with loss on ignition) that is used in grade control to assign mined material as grade blocks to high grade, low grade or waste destinations.

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 ...
