One method of exploitation of an ore mine that contains 1 million metric tons of ore will result in a recovery of 70% of the available ore deposit and will cost $25 per ton of material removed. Another method of exploitation will recover 60% and will cost $20 per metric ton of material removed. Subsequent processing of the removed ore recovers 200 kg of metal from each ton of processed ore and cost $50 per metric ton of ore processed. The recovered metal can be sold for $2.0 per kg. Which method for developing the mine is preferred to maximize total profit from the mine?

ABC, Inc. purchased for $3,800,000 a mine estimated to contain
2.5 million tons of ore. When the ore is completely extracted, it
was expected that the land would be worth $200,000. A building and
equipment costing $1,800,000 were constructed on the mine site, and
they will be completely used up and have no salvage value
when the ore is exhausted. During the first year, 750,000 tons of
ore were mined, and $300,000 was spent for labor and other
operating costs....

Landmark Coal operates a mine. During July, the company obtained
500 tons of ore, which yielded 250 pounds of gold and 63,400 pounds
of copper. The joint cost related to the operation was $500,000.
Gold sells for $325 per ounce and copper sells for $0.85 per pound.
Allocate the joint costs using the relative sales values. With
these costs, what is the profit or loss associated with Copper?

1.A stockpile of approximately 50 metric tons of plutonium
exists in the United States as a result of disassembling warheads
from the nuclear arms race. What is the likely fate of this
plutonium? (Hint: Search for plutonium disposal.
Try also including United States and DOE in your
search string.)
a. Some propose
that the plutonium be sent to local nuclear power plants to “burn”
as fissionable fuel. What are the advantages and disadvantages of
such a course of action?
b....
