“New Developments in Copper Extraction – A Perspective”

Presented by:
John O. Marsden, P.E., Phelps Dodge Mining Company

About the topic:
The copper industry has a history of extreme cyclical change which, similar to other commodities, is caused by the supply and demand balance of copper in the market place. New developments in copper extraction technology are arguably both the cause and effect of this cyclical relationship: On the one hand, successful technology developments result in lower costs of production, which in turn leads to increased copper production and consequently to a decrease in the metal price. On the other hand, a lower copper price tends to drive technological innovation as producers are forced to reduce their cost of production to maintain competitiveness in the industry. This presentation reviews some of the major technology developments in copper extraction from a historical perspective, and then discusses a number of important emerging new technological developments that will shape the future of the copper industry going forward.
