the iron ore extraction process passes through cycloning and thickening stages, and is then densified and filtered, generating tailings with a geotechnical moisture content

Sublevel stoping is the most popular and practiced mining method in underground hard rock mines. Proper planning and its execution is the key requirement for stope extraction using this method. The stope extraction has been a challenging task since decades. The major reason is the unavailability of free faces as compared to opencast bench blasting. The …

Iron mining waste is disposed of near mines and forms iron ore (hematite) tailings dams. Furthermore, the distinctive characteristics of hematite particles can affect the geotechnical properties of soil. This study aimed to experimentally examine the compressibility and small-strain stiffness of silt-hematite mixtures.

Geotechnical analysis plays an important role in determining mining method selection. This study presents the geotechnical design analysis of a potential U/G iron ore Mentes Mine at Yahyali province of Kayseri district in Turkey. Iron ore body is initially planned to be mined by using long hole mining method.

Using a combination of experimental and numerical methods, this study examines the stability of the slope of Waste Dump#1 in Ziluoyi Iron Mine. We conducted direct shear tests on soil samples taken from the waste dump, which provided important insights into slope stability. The tests identified key mechanical parameters, including an average cohesion of 4.80 kPa …
