The extraction of ore and minerals by underground mining may induce ground subsidence phenomena. These phenomena produce several types of ground movement like horizontal and vertical displacements, ground curvature and horizontal ground strain at the surface, and associated building damage in urban regions. The influence function is a well-known and efficient method for the prediction of these ...

In Chile, metal mining is concentrated between the Administrative Regions IV and VI (which includes Metropolitan Region). The northern central zones of country have abundant copper as well mineral iodine iron. Today, these residues are stored in tailing dams. Mine tailings constitute toxic composed trace elements, which many occasions deposited areas neighboring human settlements a health hazar...

LKAB’s Kiruna Mine is located above the Arctic Circle in northern Sweden, and produces about 24 million tons of iron ore per year, making it is the second largest underground mine in the world today. The orebody, a world-class high-grade magnetite deposit, is approximately 4 km long and 80 m wide on average, and lies roughly in the north-south direction, with a dip of some 60 degrees. Surface m...

Abstract The massive annual tonnage of iron ore tailings, plus the more demanding environmental policies after catastrophic collapses Fundão Dam in 2015 and Feijão I 2019, have forced Brazilian mining companies to search for sustainable safer alternatives tailings disposal. industry has been studying dry stacking filtered tailings. Most seek development great stacks, over 200 m high, absorb who...

The plant species Pinus halepensis grows spontaneously on heavily polluted mine tailings dumps of Campo Pisano (Sardinia, southwestern Italy). area is characterized mainly by Zn, Pb, and Cd. Sampling campaign was done, related to soils materials (roots, barks, wood, needles), aimed at evaluating the main mineralogical characteristics, metal content, accumulation, translocation behavior. substra...

agh darreh tailing dam located in 23 km north of takab, west azarbayjan province is used for disposal of mine tailings. the tailing dam and its reservoir were constructed on gypsiferous marlstones. this is emphasis on geotechnical and environmental importance of the site. although construction of dams on gypsum rocks were not yet prohibited, but the dissolution of gypsum in contact with water i...

In this study, a novel technology for the comprehensive utilization of low-grade iron ore is presented. For with Fe content 24.91%, pilot-scale study pre-concentration, suspension magnetization roasting, grinding, and low-intensity magnetic separation was conducted, an concentrate grade 62.21% recovery 85.72% obtained. The products were analysed using chemical elemental analysis, particle size ...

INTRODUCTION Demand for Australian mined iron ore has increased employment within this sector, thus exposing increased numbers of workers to the harsh Australian climate. This study examined the influence of hot (>30°C wet bulb globe temperature) environmental temperatures, consistent with working in North Western Australia, on iron ore mining staff. METHODS Core temperature, hydration status...
