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 following list of mines in the Philippines is subsidiary to the Lists of mines in Asia article and Lists of mines articles. This list contains working, defunct and future mines in the country and is organised by the primary mineral output(s) and province. For practical purposes stone, marble and other quarries may be
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.
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 ...
The first step involves the oxidation of the feed to form a copper matte and a lead-rich slag. The slag is then tapped and the remaining copper matte is then converted to blister copper. [57] The lead-rich slag is subsequently reduced in a blast furnace to produce lead metal, while the copper is refined and the contained precious metals ...

Refining at the mines as well as at a copper refinery in Amarillo, Texas, produce 375,000,000 pounds (170,000,000 kg) of refined copper each year. ASARCO's hourly workers are primarily represented by the United Steelworkers. ASARCO has 20 superfund sites across the United States, and it is subject to considerable litigation over pollution.
