Abstract
The authors test grinding of mining waste material to a preset grain size composition under stagewise increased destructive force and at reduced sliming. The optimized conditions are determined for disintegration of mineral and tin-bearing waste aggregates at minimized micro-size sliming. The quality of the final concentrates can be improved via mechanically activated grinding of roasting stage middlings.
