Copper production environmental impact

• Copper has low chemical reactivity. In moist air it slowly forms a greenish surface film called patina; this coating protects the metal from further attack. • Copper is easily alloyed with other metals. Currently, there are around 570 copper alloys listed. • Brasses and bronzes are probably the most well-known families of copper-base alloys. Brasses are mainly copper and zinc. Bronzes ...

purification of copper by electrolysis metal extraction ...

Copper is extracted from its ores by chemical processes that involve heat or electricity (roasting ores in a smelter–furnace and purification by electrolysis – all the details below). Because of its position in the reactivity series of metals, less reactive copper can be extracted using carbon in a smelting furnace. Copper is well below carbon (less reactive) and so can be displaced by ...
