Analysis for Magnetite Utilizing Magnetic Susceptibility - Geophysics

Thus, one unit of metallic iron would be counted as approximately 12 units of magnetite in the calculation of magnetite content. Analysis for "magnetite equivalent" and chemical analysis for total soluble iron can provide an accurate evaluation of the amount of nonmagnetic iron in any particular ore, especially in mixed magnetite‐hematite ores.
