Copper and alloys with a high copper content are recycled to obtain pure copper. The metals are heated with oxygenenriched air, which oxidizes most of the metals, but not the copper or any precious metals, forming a slag that can be removed. The Isasmelt process described above is often used for secondary copper production.
Copper slag is generated out of copper concentrate while extracting copper in the copper smelting units. It is composed of ferrosilie material and oxide when the slag is quenched in the cold water. This process makes the slag into a granule form resulting coarser and angular particles. Where is it used?

industry are increasing substantially. Copper slag is a byproduct obtained during matte smelting and refining of copper. Production of one tonne of copper generates approximately 2.2–3 tonnes of copper slag. Several researchers have investigated the possible use of copper slag as fine and coarse aggregates in concrete and its
STAR GRIT copper slag is a reputed name in the Anticorrosion Industry. STAR GRIT has been approved by several Industry leaders for our costefficient and effective performances. We source our raw materials from globally renowned suppliers.
It is estimated that in the copper industry, for every ton of metallic copper production, approximately 2.2 tonnes of copper slag is generated and in the world, about 24.6 million tons of slag is produced annually (Gorai, Jana, Premchand, 2003).
The percentage of copper slag used for replacement of river sand are 0, 25, 50 and 75 %. Cement sand mortar joint thickness of 10 and 15 mm. Plaster ability of use of copper slag for partial replacement material for river sand. Use of copper slag as replacement material for river sand in cement concrete (0, 25, 50, 75 and 100 %)
Copper slag is a copper industry waste that is essentially used as an abrasive for metals to remove coatings or paintings, due to its hardness, sieve distribution and rough surface, mainly in the naval industry.
5. Use of copper slag in cement clinker production. As shown in Table 1, copper slag has a high Fe content and has been used as an iron adjustment material during the cement clinker production (Huang, 2001).Since the main composition of copper slag is vitreous FeSiO 3, it has low melting point and could reduce the calcination temperature for cement clinker.
Ferro Sand (also known as Copper Slag) is a byproduct generated during pyrometallurgical process to produce Copper. Sterlite Copper produce approximately 6,00,000 MT of Copper Slag per annum. Ferro Sand is nontoxic, nonleachable and non hazardous material in nature.
Apr 19, 2018 · Copper slag is used in following Appliions: * Sandblasting: Copper slag is mainly used for surface blastcleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stre
Copper slag is mainly used for surface blastcleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the work piece. Copper slag is just one of many different materials that may be used as abrasive grit.
Apr 19, 2018 · Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Copper slag also has a high strengthtoweight ratio, making it an effective option in concrete, or a
CHAPTER 1 INTRODUCTION 1.1 GENERAL Although copper slag is widely used in the sand blasting industry and in the manufacturing of abrasive tools, the remainder is disposed of without any further reuse or reclamation. copper slag was used as a
Read more about Sterlite''s copper slag waste finds new uses on Business Standard. Anil Agarwalpromoted Sterlite Industries India Ltd (SIIL) is planning to convert a waste product of its copper smelting plant at Tuticorin – copper slag — into an alternative material for concrete appliions.
Energy and Environmental Profile of the U.S. Mining Industry 5 Copper For nearly 5,000 years, copper was the only metal known to man. It remains one of the most used and reused of all metals. The demand for copper is due to its good strength and fatigue resistance, excellent electrical and thermal conductivity, outstanding resistance to
Copper slag admixed mortar and concrete showed a lesser amount of leaching than solution due to the complex formation with cement mortar. Hence, copper slag can be used (2.5%) in raw mix for OPC and (35%) in manufacture of PSC. The material does not have any adverse impact on
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
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.
Industry Research I Copper Industry 3 Now the copper ore is processed according to the content the ore contains. If the copper ore is rich in sulfides it is processed through Pyrometallurgy and if the copper ore is rich in oxides it is process through Hydrometallurgy. Pyrometallurgy uses the
Can Copper Slag Be Used For Slag Cement Products . Effects of Copper Slag as Sand Replacement in Concrete Similarly copper slag is a byproduct from copper industry which can be used Cement kg/m3 Copper slag can copper slag be used for slag cement Copper Slag Shape and Texture: Aircooled copper slag aggregates are black in color, and typically have a glassy appearance.
slag, and this constitutes one of the main byproducts of the metal extraction industry . The average composition of primary copper slag corresponds to 3040 % iron, 35– 40% silica, less than 10 % of alumina and calcium oxide and copper content is around 1%Cu, similar to the ore mined.
Copper slag is mainly used for surface blastcleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece. Copper slag is just one of many different materials that may be used as abrasive grit.
Slags can be broadly egorized as ferrous (iron/steel) and nonferrous (copper, lead/zinc) depending on the industry from which they come. Non ferrous slags make up only 12% of the total annual production Described below are the main types and uses of slag commercially available in Ferrous Slag
