Ore sorting has a potential to upgrade a range of mineral ores to processing plant leading to substantial reduction in downstream costs, limiting environmental harm by reducing mine wastes and improving ore quality and mineral recovery. Ore sorting techniques give an opportunity to remove gangue and below grade ore prior to main processing step.
Sensor-based ore particle sorting offers a powerful method for pre-concentration or waste rejection early in the comminution process. The technology analyzes each and every rock particle on-line for unique physical and chemical properties and separates the particles by high pressure air jets.
