  • University of Minnesota’s Mineral Pages: Calcite

    If a mafic magma cools slowly enough, dense magnetite crystals may settle as they crystallize, to form large magnetite ore bodies with a strong magnetic character. Magnetite can also form during contact metamorphism of impure ironrich limestone, and in high temperature hydrothermal sulfide vein deposits.

  • Different Types of Iron Ore Mineral Processing Metallurgy

    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 highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
