how do you calculate the percentage of an ore? Yahoo Answers

May 02, 2008· When calculating the percentages of things like H2O, take twice the atomic weight of H because there are two of them in the molecule. If the ore contains just a fraction of PbS, multiply this fraction by the percent of either Pb or S. If the ore was 12 PbS, then the amount of Lead would be 12 times 86.6 , or 0.12 times 0.86 = 10 percent Lead.
