study the potential use of copper slag as fine aggregate on the strength of both normal and high strength concrete. Concrete mixtures were prepared using different proportions of copper slag as partial and full replacement of fine aggregate. The percentage of copper slag added by weight ranged between 10 of sand used in concrete.
Pictures of Processed copper slag for blasting. copper slag blasting is typically used for removal of mill scale, rust, paint layers, dirt and old coating; and creation of deep surface profiles or required for superior adhesion of the subsequent coatings. It can also be used as an additive for floor hardening.

Copper slag is a byproduct created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of nonmetallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
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. The slag forming reaction is: FeO + SiO 2 → 2
Oct 02, 2019· Copper slag is a byproduct created during the copper smelting and refining process.

Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
Oct 01, 2019· Copper slag is a byproduct created during the extraction of copper from copper ore. Sulfur is a common component of slag. Metals start to oxidize as they are smelted and slag forms a top crust during this process that protects the liquid metal underneath.
Copper slag is a byproduct created during the copper smelting and refining process. Copper slag is a byproduct obtained during the production of copper metal, which can be used as pozzolana in the production of cementing materials. Recycling copper slag to recover metals has been focused on copper recovery.
In the slagmaking stage, impure scrap with a lower copper content can be used, whereas in the coppersmelting stage, pure copper scrap is used, especially spent anodes from the electrolysis process. Coppercontaining scrap can also be added to the smelting stage, depending on type of smelting furnace used and type of scrap.
Description: Copper slag is a byproduct produced during smelting of copper, which is then processed into abrasive products. Typically it is composed of Ferro silicate material and oxides formed when the molten slag is quenched in cold water.
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.
Smelter slag is initially deposited in piles. These slag piles range in surface area from one to 75 acres, and in height from three to 45 meters. Slag is associated with smelter operations, which may or may not be colocated with the mines. Copper slag can be used either as sandblast grit or an admixture in concrete. Top of Page.

SLAG is a broad term covering all non metallic co products resulting from the separation of a metal from its ore, Its chemistry and morphology depends on the metal being produced and the solidification process used. Slags can be broadly categorized as ferrous (iron/steel) and nonferrous (copper, lead/zinc) depending on the industry from which ...
Copper Slag. Shape and Texture: Aircooled copper slag aggregates are black in color, and typically have a glassy appearance. Granulated copper slag aggregates are similar to aircooled copper slag aggregates but more vesicular. Gradation: Reverberatory copper slag can be processed into coarse or fine aggregate material for use in hot mix asphalt.
Abrasives processed from slags have replaced silica sands in many steel fabrication shops because of their low free silica content. Copper smelters and coalfired electric generating plants are 2 major material sources for these slag products. The chemical characteristics of the copper slags are dependent upon the
Dec 29, 2017· What is copper tailing and copper slag? There are two typical deposits which ultimately yield copper. Ores and Sulphides. Copper is typically only present at a 1% level in the mined material. In mining copper, one usually crushes the ore to a fine...
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.
demands further processing of the slag. Processing of such, copper rich slag, is facilitated using flotation or electroprecipitation of remaining sulfides resulting with about % Cu in the remaining waste slag [2, 3]. Those copper losses in the waste slag are strongly influencing the economy of the copper extraction process. Also, it is a

Properties And Effects Of Copper Slag In Concrete 46 PROPERTIES AND EFFECTS OF COPPER SLAG IN CONCRETE M. V. PATIL Applied Mechanics Department, National Institute of Technology, Surat, Gujarat Abstract: Copper slag is a byproduct obtained during matte smelting and refining of copper. This work reports an
Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs are higher, ultimately more copper can be extracted.
