Copper Recovery in Smelting Slag Recycling

Copper smelting slag is the solid waste generated in the process of smelting copper. Due to the limitations of the smelting technology, most of the copper smelting slag contains a certain amount of copper. Disposing and recycling copper can effectively reduce the waste of useful resources, while generating considerable economic effectiveness.
