Sensor-based ore sorting uses XRT, optical, laser, NIR, and electromagnetic sensors to examine individual rock particles and reject barren waste before milling, cutting energy and water use while improving head grade. This complete guide covers every sensor technology, how a sorter is engineered, the economics of pre-concentration, ore amenability testing, and the future of multi-sensor fusion and underground sorting.
Comminution in mineral processing is the progressive size reduction of ore through crushing and grinding to liberate valuable minerals from gangue. This complete guide covers the physics of fracture, classical energy laws (Rittinger, Kick, Bond), the Bond Work Index, circuit design options, HPGR and stirred mill technologies, and practical optimization strategies for improving energy efficiency.
This complete guide to grinding mills in mineral processing covers ball mills, SAG mills, rod mills, stirred mills, and HPGR technology, including design principles, circuit configurations, mill sizing methodology using the Bond equation, and grinding media selection and wear optimisation. Essential reading for mineral processing engineers designing or optimising comminution circuits.
Ore handling accounts for 30 to 60 percent of total raw material delivered cost in mineral processing plants, yet it is often underdesigned relative to its operational importance. This complete guide covers ROM ore characteristics, primary crushing, belt conveyor systems, stockpile design, feeders, bins and chutes, dust suppression, and integrated system design principles for engineers and metallurgists.
Crushers in mineral processing reduce run-of-mine ore through a sequence of primary, secondary, and tertiary stages before grinding. This complete guide covers jaw, gyratory, cone, and impact crusher types — how they work, their design features, selection criteria, capacity and reduction ratio, open and closed circuit configurations, and wear management best practices.
A complete technical guide to ore mineralogy and liberation in mineral processing: how the minerals present, their textures, and their intergrowths with gangue control liberation size, comminution strategy, flotation selectivity, and maximum achievable recovery. Covers process mineralogy tools including QEMSCAN and MLA, deportment studies, and the challenge of refractory ores.
