Mineral processing is a major division in the science of Extractive Metallurgy. Extractive metallurgy has been defined as the science and art of extracting metals from their ores, refining them and preparing them for use.
A gyratory crusher was installed in a gold mine where it was expected to crush the ore at a rate of 660 t/h. The crusher was arranged to gyrate at 140 cycles/min at an angle of 30° to the horizon. Estimate 1. radius of the cone, 2. change in throughput when the crusher was switched to dolomite (S.G. = 2.8), 3.
