 · Geometallurgy. 1. Introduction. Sensor-based sorting is a technology applied by the mining industry to reject coarse barren particles (in a size range between 10 and 100 mm) of a heterogeneous ore at an early stage of a beneficiation process ( Knapp et al., 2014; Wills and Finch, 2016; Wotruba and Harbeck, 2010 ).

Sensor-Based Ore Sorting to Maximise Profit in a Gold …

Sensor-based ore sorting is being increasingly used to reduce the amount of low-grade and waste material processed in mineral concentrators. This type of preconcentration provides bottom-line benefits to users by reducing the amount of energy, water and consumables, as well as reducing capital cost.
