The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.

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

During the last ten years great strides have been made, on the Mesabi range, in the practice of beneficiating low grade iron ore material. By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being silica and moisture. The general processes to which low grade iron ores are amenable ...
Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
Deposits of comparatively lower grade iron ore that remain relatively untouched or bypassed, are now most important because of increase in consumer demands. Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores.
Iron ore pellets are marblesized balls of iron ore that are fused with clay for transportation, and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from a lowgrade iron ore involves processes like mining, crushing, separating ...
