Abstract
The preceding chapters demonstrated how net returns per ton of ore can be calculated. They are, of course, only dependent on ore grades and not on the amount of ore mined. When considering the production costs, the output per unit of time must also be taken into account. The greater the output per day or per year, the lower are the costs per ton of ore. This effect is called “economics of scale”.
