Tailings Filtration: Water Jet Spray Cleaning of a Blinded Iron Ore Filter Cloth
نویسندگان
چکیده
The global growth in demand for raw materials is leading to a continuous increase the mining of ores and thus an expanding volume tailings be stored. To ensure safer storage optimized recovery process water, slurry often thickened followed by filtration filter presses dry stacking. However, increasing blinding effect during time operation requires cleaning or replacement media. Cloth washing using spray nozzles possible solution, but there insufficient quantitative data published on performance. For this reason, article examines iron ore cloth from water spraying. Water flux, direction (front- back-wash) variation were investigated evaluating performance flow resistance measurement comparison unused industrially used state where has occurred. Sufficient achieving rate possible. excessive should avoided, as damage fibers may occur. Spray can stated economically reasonable since 2.5 m3 m−2 energy consumption 6.5 kWh necessary sufficient regeneration. Furthermore, assumed cost USD 6 m−2, which approximately similar replacing fabric reduces plastic waste.

Reprocessing of Sangan iron ore tailings by flotation
The Sangan processing plant consists of four consecutive low-intensity magnetic separation steps with the same magnetic field intensity of 1300 Gauss for upgradation of iron ore. Hence, the iron ore minerals with lower magnetic susceptibility or interlocked with gangue minerals have no opportunity for upgradation, and proceed to the tailing dam. Flotation is a powerful technique for upgradation...
