our excessive dependence on foreign imports for our supply of these critical, strategic materials has been sounding alarms from both the cia and the usgs. rare earth metal supplies have become critical. the supply of rare earth elements is scarce not because mineral resources are low, but the process of mining them is both expensive and dangerous.
having the correct number of crushing stages helps to minimize fines is critical. for maximum efficiency, a crushing circuit will generate a reduction ratio between 5:1 and 7:1. using a two-stage crushing circuit with a reduction ratio between 3:1 and 4:1 at each stage reduces fines and also decreases the number of particles filtered back to the crusher.
