Intensifying the attrition of mineral waste in stirrer mills
Intensifying the attrition of mineral waste in stirrer mills Up to now, contaminated mineral residues—especially in the particle size range 100 μm—cannot be cleaned effectively by mechanical treatment. Therefore, a new process has been developed by modifying well-known comminution techniques in stirrer mills.
