Waste Copper Scrap RecyclingCopper Metalcess
Recycling of copper scrap greatly reduces natural resource exploration as an alternative source of copper metallurgy and has big advantage in investment, production cost and offgas treatment, thus making the copper scrap smelting projects remunerative. However, due to the wide source range, the copper scrap is classified as per its grade, to be treated by different smelting process, which is ...

From Ore to Finished Product
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.

Copper Scrap an overview | ScienceDirect Topics
In the slagmaking stage, impure scrap with a lower copper content can be used, whereas in the coppersmelting stage, pure copper scrap is used, especially spent anodes from the electrolysis process. Coppercontaining scrap can also be added to the smelting stage, depending on type of smelting furnace used and type of scrap.

One hundred years of Australian copper smelting ...
Copper smelting is typically a twostage process, with a feed of copper ore or concentrate to a roaster or sinter plant to agglomerate the concentrate and remove some sulfur. This material, along with fluxing minerals and a fuel such as coal or oil, is then fed to a furnace where a copper matte is produced.
