Copper Smelting - IFC

Copper can be produced either pyrometallur- gically or hydrometallurgically. The hydromet- allurgical route is used only for a very limited amount of the world's copper production and is normally only considered in connection with in- situ leaching of copper ores; from an environmen- tal point of view, this is a questionable.
