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.
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]
The Tampakan gold and copper deposit is situated in the mountains surrounding the town Tampakan in the South Cotabato province in the Philippines. [5] The deposit was discovered in November 1990 by the Australian company Western Mining Corporation (WMC), who acquired mining rights in Tampakan through a Financial and Technical Assistance Agreement (FTAA) with the Philippine government.

Non-ferrous slag can be characterized into copper, lead, and zinc slags due to the ores' compositions, and they have more potential to impact the environment negatively than ferrous slag. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores ...
Thus, the two factors that most affect the loss of copper to slag in the smelting stage are: matte grade; mass of slag. [35] This means that there is a practical limit on how high the matte grade can be if the loss of copper to slag is to be minimized. Therefore, further stages of processing (converting and fire refining) are required.
