The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (southwestern Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.

Efficiency of the comminution operations is traditionally assessed based on operating cost and energy consumption. Traditionally, the lowest operating cost was achieved by multi stage fully autogenous grinding due to elimination of steel grinding media costs which may represent up to 50 % of the grinding cost. Significant reduction of the cost associated with grinding was achieved over the ...

Iron ore is ground to finer particle sizes through different grinding systems. Large grinding mills using grinding ball media are one of the most common and particularly in pelletizing plants where finer particle size are required for the pelletizing process. Those large mills operate either with water mixed in with the ore – called wet grinding – or without water dry grinding. A fair ...
