Question
The world's oceans contain on average of 0.9 oz of Au /ton of ocean water. There were 2 proposed novel process in mineral extraction to recover the Au and they were compared using Engineering Economic Analysis. Process X costs $600/ton of ocean water processed and a recovery of 90%, while Process Z costs $450/ton and a recovery of 60%. Both processes will need the same amount of capital investment and equal ounces of Au extracted daily. If the Au today is $2,200/oz, which process is more feasible considering the fact that the world's ocean can be inexhaustible? This problem requires the analysis to be on the basis of profit per ounce of Au extracted.
