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...
Mathematical Model For Energy Saving In Induration Of Iron Ore Pellets Containing Solid Fuel
Mathematical model for a pilot scale iron ore pellet induration furnace has been developed which considers the process of induration including the reactions of limestone, magnetite and coke. The differential equations of energy, mass and momentum are solved simultaneously. The profiles of temperature, pressure and concentration are obtained. Performing separate experiments on sub processes; dry...
متن کاملAn evaluation of void-filling interpolation methods for SRTM data
1 The Digital Elevation Model that has been derived from the February 2000 2 Shuttle Radar Topography Mission (SRTM) has been one of the most 3 important publicly available new spatial datasets in recent years. However, the 4 'finished' grade version of the data (also referred to as Version 2) still contains 5 data voids (some 836,000 km 2) – and other anomalies – that prevent immediate 6 use i...
متن کاملUnder-mining health? Local impacts of iron ore mining in India
Environmental justice concerns about adverse impacts of extractive mining industries challenge their claim of broad-based development. However, empirical evidence of negative externalities attributable to mining enterprises is thin. In this paper, we examine the burden of Acute Respiratory Illness and Malaria among villagers along a gradient of proximity to mining areas to generate evidence per...
متن کاملBone graft expanders: filling the void.
Approximately 500,000 bone graft procedures are performed each year in the United States. The surge in the demand for graft material is largely the result of an increase in the number of spinal fusion procedures being performed. In 2001, only 22,000 bone donors existed worldwide, suggesting a shortage of available allograft in the future. This has led to the growing demand for bone graft substi...
