Mine Tailing - an overview | ScienceDirect Topics

The mine tailings are usually dumped directly in their final location (see figure 4), using a hydraulic crane on a pontoon.In some cases the mine tailings are to be dosed using a stone classifier, and they are then discharged at an intermediate point. These methods allow the use of the mine tailings without intermediate storage (“one-to-one production and use”).
