Benson Mines Wikipedia

Ironore deposits that contained 50% or more iron were depleted in the United States by the mid1940s. The ability to concentrate “nonmagnetite ores by gravity processes” at Benson mines ensured its economic expansion because these processes enabled lower grade iron ore to be used in steelmaking.

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.
