Development of ore sorting and its impact on mineral processing
Run-of-mine molybdenum ore was sorted using a dual energy X-ray transmission array. • Sorting thresholds permit optimization of Mo recovery and waste rejection. • Mo recoveries of 65.6–93.4% and waste rejection of 40.2–93.7% were achieved. • Two comminution circuits were proposed to evaluate ore sorting impact on operations. •
