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.

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 → FeO.SiO 2

In the slag-making stage, impure scrap with a lower copper content can be used, whereas in the copper-smelting stage, pure copper scrap is used, especially spent anodes from the electrolysis process. Copper-containing scrap can also be added to the smelting stage, depending on type of smelting furnace used and type of scrap.

Sep 26, 2019· Manufacturing Process of Copper . ... and bring them to the surface to be removed as slag. The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper.

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 the performance of OPC and PSC. The users of copper slag in OPC / PSC can be assured of the non-leachability of copper and other elements.

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 non-ferrous (copper, lead/zinc) depending on the industry from which ...

Copper slag is a by-product created during the copper smelting and refining process. Copper slag is a by-product 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.

Abrasives processed from slags have replaced silica sands in many steel fabrication shops because of their low free silica content. Copper smelters and coal-fired electric generating plants are 2 major material sources for these slag products. The chemical characteristics of the copper slags are dependent upon the

demands further processing of the slag. Processing of such, copper rich slag, is facilitated using flotation or electro-precipitation of remaining sulfides resulting with about 0.5% 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

Can copper slag be reused for sand blasting? Yes. ... The process of extracting copper of copper carbonate The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen ...

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 co-located with the mines. Copper slag can be used either as sandblast grit or an admixture in concrete. Top of Page. EPA and the States

Aug 20, 2014· Many investigators have conducted and also showed that the use of copper slag aggregate compared to limestone aggregate resulted in a 28-day compressive strength improvement of about 10–15 % . Therefore, copper slag can be beneficially used as partial replacement for river sand as a fine aggregate in brick masonry construction.

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 .

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic 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.

Can The Copper Slag Be Used Instead Of Sand In ConcreteHow to Use Slag eHow. How to Recycle Copper Slag. has become a popular and cheap alternative to sand for use in concrete is a form of sustainable concrete that can b

Copper Slag. Gradation: Reverberatory copper slag can be processed into coarse or fine aggregate material for use in embankment applications. Copper slag can readily satisfy the gradation and physical requirements of AASHTO M145. (11) Unit Weight: Copper slag has a unit weight of 2800 to 3800 kg/m 3 (175 to 237 lb/ft 3).

Copper slag is mainly used for surface blast-cleaning. 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.

Copper Slag. Shape and Texture: Air-cooled copper slag aggregates are black in color, and typically have a glassy appearance. Granulated copper slag aggregates are similar to air-cooled 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.
