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 ....
