Grindability Studies of Mineral Materials of Different

2019-8-24  These studies have been carried out to compare the grinding characteristics of different morphological mineral matters. Coal, dolomite, manganese and iron ores samples were ground using a ball mill in different grinding conditions (dry and wet) and at different critical speed (R 45%, R 70% and R 90%) during wet grinding.

Major Mines & Projects Carol Lake Mine

The grinding is currently done in four wet mills. Ground ore is then concentrated in the spiral plant using gravity spirals to increase the iron content from 38% to approximately 65%. The spirals utilize the forces of gravity, centrifugal action and friction to separate the heavier iron ore grains from the lighter waste rock particles.
