Abstract
In the preceding chapters we demonstrated how net returns per tonne of ore can be calculated. They are, of course, dependent only on ore grades and not on the amount of ore mined see also (Chap. 5). 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 tonne of ore. This effect is called “economies of scale”, which was first described by Young (1928). The converse of an increased rate of production is a shorter life for the mine.
