flowsheet of copper scrap recycling Prominer
Recycling of “used” scrap accounts for 10–15% of copper consumption In addition to this used scrap there is considerable recycling of manufacturing wastes about 15–20% of copper consumption About one third of the scrap is rerefined to pure copper and about The flowsheet construction step is intended to review every existing combination of unit processes, ie every flowsheet that can be used to transform one specific type of scrap into refined copper, together with the associated impacts (cost, environmental impacts, energy consumption, copper Multicriteria optimization of copper scrap Recycling of copper is based on a large variety of raw materials, ranging from lowgrade copper scrap containing only a few percent Cu to very highgrade copper as well as pure copper close to 100% Cu (Table 71) Thus there are several options for recycling processes, within both primary plants and secondary plants treating only scrap materialCopper Scrap an overview ScienceDirect Topics

Copper Recycling Flow Model for the United States
Overall, there is a substantial potential to increase the recycling of copper by recovering more coppercontaining scrap and recycling it more efficiently, that is, with a higher yield for current products with lower EoLRR like consumer and electronic products, but the energy savings are not as high as one might expect because more of this scrap is lower grade and hence requires more energy to be recycled than the highgrade scrap that dominates current recycling On the basis of information provided by the Union Miniere Company , Fig 1 presents a coppersmelting flowsheet for the recycling of scrap IC boards Download : Download fullsize image; Fig 1 Union Miniere Company's coppersmelting flowsheet for recycling of scrap IC boardAn overview of recycling and treatment of scrap In this paper, a detailed thermodynamic analysis of processing of electronic waste (ewaste), particularly printed circuit boards (PCB), through secondary copper recycling (black copper smelting), was carried out The mass balance flowsheets of two scenarios, ie, the case of secondary copper recycling with (SCE1) and without (SCE2) addition of PCBs, have been developed and compared From the Thermodynamic analysis of metals recycling out of
