Iron Ore Beneficiation Process

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 ...

Mining yield - UniWiki - Eve University

Mining yield is the rate at which miners mine ore, ice, or gas.As all mining modules mine a certain volume of ore/ice/gas in a given time, the amount of ore/ice/gas mined therefore depends on this mining rate (often quoted in m 3 per minute) and on the volume of the ore/ice/gas (m 3) being mined.

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.
