To fulfill the objective six open pit iron ore mines were chosen where lateritic material is being removed by single shank ripper dozers. The field and laboratory investigations were performed and found that the ore rock is having uniaxial compressive strength between 5.09 to 22.65 MPa, point load strength between 0.54 to 3.22 MPa

DEM study of the mechanical strength of iron ore compacts

Sep 10, 2015 Iron ore fines are created as a result of mining, crushing and processing large iron ore particles, and may account for 50% of the total ore mined. For many processes (e.g. iron-making), lump ores (size larger than 10 mm) are preferred since fines not only increase the cost of handling but also suppress the air flow in a blast furnace

The strength properties of green sinter beds, including the Young’s modulus and maximum bed strain, were evaluated using uniaxial compression tests. The green-sinter-bed samples were scanned using X-ray computed tomography (XCT), and the geometry characteristics of the granules were quantified by XCT image analysis.

Compressive strength Wikipedia

The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hooke's law.Hence, for this region, =, where, this time, E refers to the Young's Modulus for compression.In this region, the material deforms elastically and returns to its original length when the stress is removed.
