Which of the following is not an ore of iron?

Note: Iron formation consists of ore like siderite, magnetite, and hematite, with silica within the variety of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of ore are sometimes high-grade but are often mixed with an honest deal of silica, the full making an ore too lean to be used without concentration.

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.
