Use your calculations from the previous page to label the points on the graph ==> NOTE THE LOG SCALES! log (concentration factor) O -8 -6 -2 -4 log (crustal abundace) Draw a line through the data. Explain the trend on the graph. 0 N Suppose that you have inherited 100,000 metric tons of Chalcopyrite ore from your great aunt who was the owner of a mining company. Calculate the number of metric tons of pure copper that are contained in the ore. Assuming a market price of $2,500 per metric ton of Cu how much would the inheritance be worth? Note: Chemical formula for Chalcopyrite is CuFeS2 3
