Effect of Copper Slag and Recycled Aggregate in the ...

 · Copper slag must have a sufficient quantity of lime to reach the required rate of hydration and to achieve the required early age strength. Therefore, in this case, in order to increase its Pozzolanic reaction, hydrated lime was added up to % to the weight of cement. Copper slag has high concentrations of SiO2 and Fe2O3 compared with OPC.

Life Cycle Assessment of Recycling Copper Process from ...

 · The predigestion life cycle assessment (LCA) method has been applied to investigate the environmental impact of the recycle copper process from copperslag. Related environmental load data of each process stage have been obtained. Copperslag recycle copper process includes crushing, milling, flotation, dehydration. Environmental impact single data of each process stage is, .

MANAGEMENT WASTE

process, copper slag grit breaks into smaller particles and gets contaminated or mixed with rusts and paints, but there is no change in chemical composition. Prior to the setting up of the recycling plant in 1990, there was no process to separate the used copper slag from other impurities. Instead, the waste copper slag with all the contaminants

Literature review on copper slag and recycled aggregate S. Muneera et. al. (2016) studied on the Use of Recycled Aggregate in Concrete. In this study the natural concrete is replaced by recycled coarse aggregates at different percentages of 10%, 20%, 30%, 40%, 60%, 75%, .

Copper Slag

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.

Use of recycled copper slag for blended cements

 · Copper slag and fly ash reduce the heat of hydration more effectively than silica fume in mortars. The replacement of 30% cement by copper slag reduces the flexural and compressive strength in a similar way to fly ash; however, after 28 days, the reduction is less than the percentage of substitution. Hydrated calcium aluminate phases were ...

A Study on Reduction of Copper Smelting Slag by Carbon for ...

Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process, and about million tons of copper slag is generated annually in Korea. Oxides in copper smelting slag include ferrous (FeO), ferric oxide (Fe­2O3), silica (SiO­2 from flux), alumina (AI2O3), calcia (CaO) and magnesia (MgO).

Recovery of metal values from copper slag and reuse of ...

Copper slag was characterized and processed. The pyrometallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440°C) helped recover a majority of the metal values (, Fe, Cu and Mo) into the ironrich alloy product which can be a feed material for steel making.

Recycling of Copper

Where copper and copper alloy scraps are very contaminated and unsuitable for simple remelting, they can be recycled by other means to recover the copper either as the metal or to give some of the many copper compounds essential for use in industry and agriculture. This is the usual practice for recovery of useable copper in slag, dross or mill ...
