1. A 20,000,000-ton ore body contains the copper (Cu) ore mineral bornite. The cost of producing the ore is $85 per ton. The pertinent information is below Ore Mineral, Chemical Composition, Percent Commodity Price of Metal Bornite Cu,FeS, 1.5% Copper (Cu): $7,069 / ton Waste rock 98.5% Atomic masses: Cu = 63.546 Fe = 55.845 S = 32.065 Perform the following calculations. Don't forget to divide all percentages by 100 (move decimal 2 places to the left) before you put them into the equations. Show all your work, or the problem is automatically wrong. a.
