Iron constitutes only about 6.2% of the continental crust's weight but makes up about 30% to 60% of iron ore. The concentration of a useful metal in an ore determines the grade of the ore the higher the concentration, the higher the grade. Whether or not an ore of a given grade is worth mining depends on the price of metal in the market.
