hematite and magnetite3b the carbonate siderite

Mechanical properties of siderite and hematite from DFT

Aiming to reveal the easy-sliming mechanism of siderite in the grinding process of carbonate-bearing iron ores, mechanical properties of siderite and hematite were computed by density functional theory (DFT). Elastic constant matrixes were developed and results show that shear deformation is the easiest deformation type compared to other types

Mechanical properties of siderite and hematite from DFT

Jan 15, 2020· From Table 1, the values of siderite and hematite are 25.46 and 5.71 GPa, inferring the distribution of Young’s modulus of siderite is more asymmetric than hematite, which is verified by the side views of Figs. 3(IV) and 4(IV). It also can be seen that the surfaces of siderite and hematite exhibit extreme variations in Young’s modulus.

Hematite Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C

Banded Iron Formations BIF Geology In

Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock that are almost always of Precambrian age. A typical BIF consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe3O4) or hematite (Fe2O3), alternating with bands of iron-poor shales and cherts
