This method was used till the mid twentieth century (Figure 19) when it was replaced by a variety of other methods based on electrostatic properties, radioactivity, X-ray fluorescence, etc.

Minerals Free Full-Text Sensor-Based Ore Sorting

While the deposit qualities for mineral raw materials are constantly decreasing, the challenges for sustainable raw material processing are increasing. This applies not only to the demand for minimizing the consumption of energy, water, and reagents, but also to the reduction of residual materials, especially fine and difficult-to-landfill materials. Sensor-based ore sorting can be used as a
