*Chapter 23 (Costs of Extracting Copper) in Extractive Metallurgy of Copper (Biswas and Davenport) is a good general and timely summary of capital and operating costs. *The following readings, about a proposed mining development in Kakadu National Park, Australia, give an interesting scenario for the discussion of how to place a value on treasured places:
· The average 'new' copper cable contains some 30% recycled material. The more we recycle, the less we need to mine. As mining costs increase because 'easy' mineral deposits are becoming scarcer and as technological improvements make recycling more competitive, the impact of urban mining on the traditional mining sector grows.
copper removal by precipitation is not as effective with lower concentrations, such as the copper level entering the Gardner WWTF. With almost all possible solutions exhausted, the potential for applying for a new permit from the EPA is another efficient way of obtaining copper .

· How is copper extracted from an open pit mine? Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining.
