The major phase of the ore was identified as magnetite by referring to the ICDD data base (PDF number 01-089-0691). As shown in Figure 1(b), the product obtained after grinding, according to the suggested method, resulted in a solid material rich in magnetite. There are no detectable crystalline impurities in the final product.

Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the ...

12%Investigations have been carried out to evolve a grinding aid useful in grinding a 40% iron-bearing magnetite containing quartz as the major gangue, based on studies conducted with pure magnetite, pure quartz and its synthetic mixture.These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz …

Magnetite ores from the Braemar iron region are notable for being comparably softer than magnetite ores from the other iron regions, enabling grinding to finer grain size without incurring significant additional power inputs.

and non-magnetic component were analysed and compared to the bulk ore. It was found that grinding properties differ significantly and therefore separate grinding test work may be required for each grinding step in the magnetite ore beneficiation flowsheet. Keywords: grinding, iron …
