Determination of Young's Modulus and Poisson Ratio of Lump Ores

Abstract

Mechanical properties of iron ores are measured under the compression test.
The results obtained are as follows:
(1) Young's modulus of iron ores is proportional to the apparent specific gravity respectively. And the Young's modulus of the hematite shows considerably higher than that of the magnetite.
(2) Young's modulus of iron ores can be expressed as a straight line, independent of the ore brand, when it is indicated against the porosity.
(3) Poisson ratio of hematite and magnetite is 0.24 and 0.33 respectively.
(4) There is a remarkable difference of Young's modulus between pellet and iron ore.
