An estimated 80% of all copper ever mined is still in use today. [15] In volume, copper is the third most recycled metal after iron and aluminium. [16] As of 2023, recycled copper supplies about one-third of global demand. [17] The process of recycling copper is roughly the same as is used to extract copper but requires fewer steps.

A penny, on its face, is worth one cent. $0.01 U.S. dollars. On the other hand, that same penny -- if melted down for the copper it contains -- could be worth quite a bit more.

Once collected, the materials are sorted into types – typically metal scrap will be crushed, shredded, and sorted using mechanical processes. Metal recycling, especially of structural steel, ships, used manufactured goods, such as vehicles and white goods, is an industrial activity with complex networks of wrecking yards, sorting facilities ...
The process used at the Lünen smelter involves charging the furnace with copper residues and scrap containing between 1 and 80% copper and then melting it in a reducing environment. This produces a "black copper phase" and a low-copper silica slag. Initially the black copper was converted to blister copper in the ISASMELT furnace. [57]
Copper slag is created during the copper smelting process. Around 4.5 million tons of copper slag is produced each year. Although copper slag is used in grit blasting and landfilling, only 15 to 20% of it is being used as of 2015. Since this is a heavily wasted material, finding ways to use it in different industries can reduce overall waste.
