The Role and Importance of Geotechnical

The value of open pit mining operation is primarily driven by ore vs. waste strip ratio. The less waste to move to extract ore, the higher the revenue that open pit mine generates. Open pit slope geometry (or slope angles) is at the core of mine design, it is determined based on rock mechanics principles by geotechnical engineers.

Geotechnical engineering for heap leach operators

Considering that the mining sequence will deliver different ore types in different relative proportions over time, targeting a specific blend will not always be practical. Nevertheless, characterizing the geotechnical and metallurgical properties of each ore type will allow the definition of the operating window, the customization of

Geotechnical Considerations for Mining Method

Iron ore body is initially planned to be mined by using long hole mining method. Detailed geotechnical site investigation and laboratory work are carried out to assess the applicability of the selected mining method. Diamond-drilled borehole cores are logged and geotechnical characterization of rock mass units is conducted by assigning RMR89 and Q classification values to the basic rock units.

Geotechnical and Hydrological Characterization

Rock samples were also collected from already drilled boreholes for iron ore estimation from a depth of more than 200 m. The laboratory testing has classified alluvium as silty sand/sandy silt (SP-SM/SM) and clayey silt/non-plastic silt (CL-ML/ML) as per soil classification criteria having angel of friction of 31.4 - 38.5 degree with bulk density of 1.461 - 1.853 g/cc.

Integration of Geological and Geotechnical

What has become increasingly apparent is that physical rock properties and geotechnical parameters need to be incorporated into the three-dimensional geological model to create an integrated mine model. The approach to the collection of geotechnical information is not as highly prescribed and controlled as collection of geological data.

Geotechnical cleaning of groundwater using reject

01-02-2021  Reject of iron-ore slime (RIOS) was collected from slime ponds of Joda East Iron-ore mines (Tata Steel Ltd. India). These fines containing 25%–30% moisture were heated in an oven (100 °C–105 °C) for 24 h to make it devoid of any moisture. Then it is further powdered in the ball mill and stored in a moisture free environment for further use.

Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H 2 O), 55% Fe) or siderite (FeCO ...
