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.
This complete guide to industrial screening in mineral processing covers vibrating screen types (banana, trommel, high-frequency, grizzly, sieve bend), screen panel and aperture selection, screening efficiency measurement, capacity sizing methodology, wet versus dry screening, the role of screens in closed-circuit grinding, common operational problems, and modern innovations including flip-flow screens, DEM simulation, and digital monitoring.
Dewatering in mineral processing encompasses thickening, filtration, and centrifugal separation to remove water from concentrates and tailings, recover process water for recycle, and prepare products for shipment or storage. This complete guide covers conventional, high-rate, and paste thickeners, vacuum and pressure filters, centrifuges, flocculant selection, water balance management, product moisture specifications, and troubleshooting of the most common dewatering failures.
Tailings management in mining encompasses the safe storage, water management, environmental control, and eventual closure of tailings storage facilities, as well as the emerging opportunities to reprocess legacy tailings for residual value. This complete guide covers all disposal methods from conventional slurry dams to paste and dry-stack tailings, dam safety principles and lessons from the Mariana and Brumadinho failures, acid rock drainage prevention, and the financial and regulatory framework for responsible closure.
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.
Sampling and mass balancing are the analytical foundations of metallurgical accounting and process control in mineral processing. This comprehensive guide covers Gy’s Theory of Sampling and the Fundamental Sampling Error, the sources and minimisation of sampling errors, automatic sampler design, slurry and solid sampling systems, the two-product formula, weighted least-squares data reconciliation, and process control instrumentation for concentrators.
