Simulation of wet ball milling of iron ore at Carajas

2007-10-19  The mill was filled with a formal ball filling ( JT) of 0.2 volume fraction (20%) and rotated on a roller table at 70% of critical speed. The formal definition of J assumes that the porosity of the ball bed at rest in the mill is 0.4 so (1) Mass of balls = 0.6 J V ρ b where V is the mill volume.

Crushing and milling Mining of mineral resources

The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal.
