Recovery of coal particles from a tailing dam for environmental
Considerable amounts of coal particles are accumulated in the tailing dams of washing plants which can make serious environmental problems. Recovery of these particles from tailings has economically and environmentally several advantages. Maintaining natural resources and reducing discharges to the dams are the most From mine face to eliminating tailings ponds, McLanahan provides solutions for both surface and underground coal mining in all aspects of the operation. The company offers a full range of feeding, crushing and sampling equipment, as well as washing and dewatering systems that can remove impurities and increase the heating value of your coal.McLanahan Coal

the aim is to recover -0.5 mm coal from dam of Tunçbilek/Kütahya coal washing plant tailings and investigate the effect of hydrocyclone parameters on coal enrichment. Ash content and coalThe freshly mined coals that are fed to coal preparation plants are typically crushed to liberate rock before washing and to limit the largest size of particles that enter the plant. Operators prefer to keep the particles as large as possible (usually >50 mm) since fine coal processes are considerably less efficient and substantially more costly.Coal Preparation SpringerLink

The objective of solid-liquid separation in thickeners in coal preparation plants is to obtain both a clear supernatant liquid with a low turbidity for reuse and a dense slurry. It is importantReal time dynamic simulation provides a powerful tool to control the mineral processing plants with the minimum cost. In this study, the dynamic simulation was carried out for the thickener at coal washing plant. Therefore, the parameters of the phenomenological model for the sedimentation and thickening were determined at Dynamic simulation of tailing thickener at the Tabas coal washing plant
