Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that and around 4 million tons of slag are disposed every year and another 40 to 45 million tons are historically cumulated. Copper slag contains iron in the range of 42 to 45%,
Copper slag is a byproduct of copper extraction by smelting, impurities become slag which floats on the molten metal. Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as discussed below.

Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractorylined furnace of either the hearth or ...

depending on the method used to clean the final slag of the pyrometallurgical process. Eventually, minor amounts of zinc, molybdenum and noble metals such as gold and silver are presented. Since, final copper slag contain around 1% of copper, its recovery from the slag could be economically accepted if no expensive treatments are found, such as
The copper is being produced from a copper concentrate containing around 30 35% of copper, iron and sulphur each along with around 12% of silica and 5% of calcium. While producing copper the anode, a slag with rich iron and moderate silica content is also generated.
The present paper provides a brief overview of copper smelting in Southern Africa. Ancient History of Copper Smelting Smelting history goes back at least 6000 years to the copper smelters of the Timna valley near Eilat in Israel. Copper is the world''s oldest metal .
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) ... This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities. The copper matte created by the smelting furnace contains 5860% copper.

Copper slag can also be used as a building material, formed into blocks. Copper slag is widely used in the sand blasting industry and it has been used in the manufacture of abrasive tools. In general, the spent copper slag is suitable to be used as a fill material for land reclamation.

In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed.

Copper extraction Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature.
iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in .
