The production of copper typically includes the following processes: Leaching Solvent Extraction Smelting Leaching There are two main leaching methods: heap leaching and in-situ leaching. Heap leaching is the most common method used in the U.S. When processing copper through heap leaching, vast quantities of ore and overburden are mined.

Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.

The alternative to blasting with copper slag

Copper slag is one of the possible abrasives that can be used. Other blasting media that can be considered are sand, glass, plastic or water. Blasting with copper slag is generally done for two different purposes. First of all, copper slag blasting is an effective way to remove mill scale, rust, dirt, paint and other coatings from metal surfaces.
