Ore - Wikipedia

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.

What Are the Different Uses of Iron Ore? (with pictures)

 · Manufacturers distinguish between high and low grade ores that contain different impurities mixed with the iron and determine the end uses of iron ore. When sites with iron ore are identified, engineers and geologists study the rock to learn more about the specific type and determine the potential yield from the mine.

uses of extremely low grade iron ore

Iron Ore - Mineral Fact Sheets - Australian Mines Atlas. At many operating mines, including Mount Tom Price, Paraburdoo, Mount Whaleback and Christmas Creek, ore processing facilities (OPF) have been constructed to enable beneficiation of low-grade iron ores, including ores which have been contaminated with shale, to be mined and, after upgrading, sold as high-grade products.

Iron ore - Wikipedia

Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is ...
