· Over the years, improved techniques have steered operators away from simple blast mining to safer and more reliable methods, such as longwall mining, as How Stuff Works explains. Here, rather than drilling through an ore deposit, a longwall machine slices off giant slabs of the material, which fall directly onto a continuously moving conveyor belt to a processing machine.

Although the iron ore contained more than 10 percent manganese, the manganese was never economically feasible to recover because it was too difficult to separate from the iron. New technology, which involves in situ leaching of the manganese while leaving behind the iron, has been investigated as a possible mining method." (6) Average grades for the shipped ores .
