environmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Continuous Fluidized Bed Drying With and Without Internals: Kinetic Model
Spirals as internals are utilized to reduce the axial mixing of solids in fluidized beds, by routing the solids flow in a predetermined route or by localizing the solids mixing. The drying kinetics of continuous fluidized bed with and without internals has been compared and modeled using batch drying kinetics and residence time distribution analysis. The batch drying experiments were conducted ...
متن کاملHydrodynamic Characteristics of Dry Beneficiation of Iron Ore and Coal in a Fast Fluidized Bed
Iron ore and coal are the two major important raw materials being used in Iron making industries. Usually ore fines containing around 5% Alumina are rejected due to higher proportion of alumina. Therefore, a technology or process which may reduce the alumina content by 2% by beneficiation process will be highly attractive . In addition fine coals with ash content is used nearly 12% is directly ...
متن کاملAn Investigation on the Reduction of Iron Ore Pellets in Fixed Bed of Domestic Non–Coking Coals
In this study, the isothermal reduction of iron oxide pellets, made of Iranian Chadormalo, Gole-gohar, and Sangan iron ores, was investigated in the temperature range of 900-1100°C. Tabas, Pabdana, Babnizoo, Karmozd, and Shahrood domestic coals were used as reductants. Parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...
