To fix for the amount of steel (Fe) that deserve to be recovered indigenous iron ore (Fe2O3), us will use stoichiometry procedures.

We can additionally look in ~ the partnership of Fe v Fe2O3. In one mole of Fe2O3, there are two moles of Fe atoms. 

First, transform the massive of ore in grams. We recognize that 1000 grams = 1kg, because of this 639 kilograms is equal to 639,000 grams.

`639,000 grams Fe2O3 * ((1 mol e Fe2O3)/( 159.69 grams Fe2O3)) * ((2 mol es Fe)/(1 mol e Fe2O3)) * ((55.85 grams Fe)/(1 mol e Fe)) `

`= 446,968 grams Fe `

Finally, convert earlier the fixed of Fe in grams come kilograms. 

447 kilograms that Fe deserve to be recovered.
