    efficiency and reduced cost per ton hauled – is not in itself problematic, it is the route, or process followed to achieve these savings that needs to be carefully managed. We can be guided on this journey by our understanding of how a road design is developed, and, critically, the interplay between a good design and safe, cost efficient haulage.

  • Innovations: Introduction to Copper: Mining Extraction

    Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.

  • Abstract

    Block caving requires a large capital expenditure for development and is usually applicable for large-scale projects. This method usually has a lower operating cost per short ton than any other underground method, and often the highest capital cost. The ore body must have enough horizontal area to cave freely, without dilution from the sidewalls.

  • Metal prices as a function of ore grade

    From 1889 to 1919 it is estimated that the L+C unit cost of minerals declined at the rate of 1.2% per year; from 1919 to 1957 the rate of decline was 3.2% per year. In summary: instead of increasing costs in the minerals industry as called for by the scarcity hypothesis a declining trend of cost was experienced.
