Apr 20, 2019· The leaching liquor and residue would be processed by corresponding methods for recovering heavy metal (Pb, Zn, etc.) or stabilizing hazardous element (As). Secondary reduction slag after recycling of iron can be reprocessed as a clean and harmless function material, comparing with the traditional waste copper slag (Heo et al., 2016).
Slags can be broadly categorized 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 products. Iron Blast Furnace Slag (BFS)

From the it was observed that the copper slag admixed concrete showed higher corrosion rates than normal concrete in various percentages of replacements. The corrosion rate of copper slag admixed concrete increases as percentage of copper slag increases. The corrosion rate can be controlled by coating the bar with Zinc Phosphate paint.
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.
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...
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. EPA and the States
Oct 02, 2019· 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.
Roughly BOF slag, EAF slag and SMP slag can be defined as steel slags. Reviewing the past, utilization of ironmaking slag has a long history. The broken slag from ironmaking was already REUTER, M., XIAO, Y., and BOIN, U. Recycling and environmental issues of metallurgical slags and salt fluxes. VII International Conference on Molten

The feasibility of the use of copper slag and recycled concrete aggregate as substitutes for aggregates in CIR mixes was investigated. Effects of different additives such as Portland cement, FA, and RHA were studied. Copper slag and different additives improved the durability and mechanical properties of CIR mixes.
Oct 15, 2015· Read "Effects of copper slag and recycled concrete aggregate on the properties of CIR mixes with bitumen emulsion, rice husk ash, Portland cement and fly ash, Construction and Building Materials" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.
Sand is the least expensive nonreusable media. Alternatives to sand abrasives include other mineral sands with no free silica, metal slag, and coal slag. Coal slag has been used frequently as a blasting material. Media of these types may not be reused in the abrasive process, but can be recycled into other materials ( cement or concrete).
Copper slag is a byproduct obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date.
Slag: The AllPurpose Aggregate. Slag is sometimes erroneously classified as industrial waste. In fact, this product can be recycled into valuable, versatile construction materials for green use. We utilize slag, a product of steelmaking, in versatile construction material for environmentally beneficial use.
Secondary copper can be used for the manufacture of these materials, though still within stipulated quality limits for impurities. Where scrap copper is associated with other materials, for example after having been tinned or soldered, it will frequently be more economic to take advantage of such contamination than try to remove it by refining.
As stated before, slag once was just dumped without any consideration to the effects to the environment. Slag is not just the hazardous waste it once was thought of. Slag contains reusable lime and metallic scrap that can be reused, in addition, being able to completely recycle it will save on cost of fuel, dumping, and transportation.
Sustainable Construction. Recycled Materials for Construction. Washed Copper Slag. Copper slag is a byproduct of copper production from copper ore. During smelting, a molten pool of copper forms at the bottom of the furnace while a layer of impure metal, which is the slag, is drained off from the top.
Copper smelting slag is the solid waste generated in the process of smelting copper. Due to the limitations of the smelting technology, most of the copper smelting slag contains a certain amount of copper. Disposing and recycling copper can effectively reduce the waste of useful resources, while generating considerable economic effectiveness.
Jun 15, 2018· Recycled copper slag is a unique option that you can use as a recycled aggregate in your next project. Durable, attractive, and recycled, these options could help push you toward a LEED certification. But what exactly is copper slag? Copper slag is a byproduct of copper smelting. Smelting is the refining process that copper ore goes through.
THIS IS A HIGHER DENSITY THAN COAL SLAG AND WILL THUS BLAST FASTER THAN COAL SLAG, AND YOU CAN RECLAIM IT A COUPLE OF TIMES AS WELL. THIS IS NOT THE CASE WITH COAL SLAG, WHICH HAS A LOWER DENSITY OF AROUND 90 's/cubic ft. Copper slag is a hard, cubical, and aggressive sandblasting media. Contrary to its name it contains almost no copper.
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.
Sep 28, 2019· The easiest way to recycle copper is to find a local facility in your area that accepts scrap copper, since even small pieces of it can be recycled. The first step in being able to recycle copper is to collect and save scrap copper in any form. Copper can be obtained from old electrical wiring, copper pipe from home remodels, and even auctions ...
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.
