Copper production environmental impact . Key points • Copper is malleable ductile and an extremely good conductor of both heat and electricity. Evidence of copper smelting has been found in Serbia from around 5000 BCthough it is thought that smelting occurred in a variety of locations in Asia and Europe at about the same time.

SmeltingWikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores including silver iron copper and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind.

An Overview of Copper Smelting in Southern Africa

Cyprus lasted for more than 3500 years and produced more than 200 000 tons of copper metal. Many slag heaps remain to this day. O okiep Copper Company By contrast the earliest records of large-scale copper production in South Africa date back to the second half of the 1800s when the Cape Copper Company began smelting copper ore from

Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example Cu 2 O FeS → Cu 2 S FeO. Impurities form a slag which floats on the surface and is easily removed. One of the reactions to remove iron impurities is shown below

PHYSICOCHEMICAL CHARACTERIZATION OF COPPER SLAG

The average of slag production in Chile is 2.2 ton per ton of blister copper produced but this figure could cover approximatly a range from 2 to 5 ton of slag/ton of blister copper in other smelters of the world. Physico-chemical characterization plays an important role in understanding the behaviour of slags
