The average multi-family unit uses 278 lbs. of copper. How much copper is needed for an apartment complex that contains 20 buildings with 16 units per building? What mass of rock (in lbs., tons, and kilograms) will need to be excavated? 2. Recall that, in 1880, copper-bearing rocks needed to contain at least 3% copper to be considered economic ore, but as of 1970, rock containing only ~0.3% copper is considered economic ore. What might be attributed to the decreased percentage? 3. In a few short sentences, describe in geologic terms what this area would look like if the rifting of the North American continent had continued? 4. The mines of this district produced over 15.5 billion pounds of copper from 380 million tons of ore. What was the overall grade of ore mined from this region? 5. Only about 40% of the total estimated copper contained in the deposits of the Keweenaw area has been mined out. How many more pounds of copper could be mined? Report your answer in scientific notation. 6. Along with copper, the area also produced 11 million pounds of native silver from same mass of rock in Question 4. What was the overall grade of silver produced? Report your answer in ounces per pound. 7. Recall that copper is second to silver for conducting electricity. Why isn't silver used in house wiring?
