Sensor-based sorting is typically used for particle sizes ranging between 0.5 to 300 mm. By separating the valuable minerals from the waste rock early in the mining process, the overall efficiency of the mining operation is improved, as less energy is required to process low-grade ore. The most widespread sensor sorter in the mining …
