Different Types of Iron Ore - 911metallurgist

Oct 05, 2016  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 concentration.

IRON ORE STEEL -- MONARCH INTERNATIONAL

The iron itself is usually found in the form of magnetite (Fe3O4) or hematite (Fe2O3), both of which are iron oxides. However, as much of the pure magnetite and hematite ore has already been mined, modern iron mines rely on aggregate ores such as taconite, which must be processed to remove non-iron-bearing components prior to smelting.
