To enable a near real-time classification of iron ore formations and grade estimation from petrophysical logs a different proxy for iron content is needed. As introduced previous, the spectral gamma-gamma ratio may be a better candidate to estimate iron content in iron bearing formations and we tested this hypothesis on SGG data from the second ...

Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without ...

Description and properties of common iron ore minerals. Iron ore minerals are rocks or minerals that contain iron in concentrations high enough to be economically extracted. Common iron ore minerals include: Hematite (Fe2O3): Hematite is the most abundant and important iron ore mineral. It is typically steel-gray to black in color and has a metallic luster.

Classification of iron ore is very important in petrogenesis. One method of classification is to compare elemental profiles using principal component analysis (PCA) . PCA is a multivariate data analysis technique and helps to find hidden patterns in large datasets. PCA was applied on the elemental profile data containing 5 samples and 35 elements.
