Different Types of Iron Ore911metallurgist

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.
