RECOVERY OF COPPER FROM BRONZE SCRAPThis paper is concerned with the recovery of copper from bronze scrap containing 910 % by weight lead and 89wt % tin by melting of scrap with or without additives and periodic removal of slag. The slag including PbS, Cu, SnO2 was leached with acid or alkali to recover black copper for improving the overall yield of copper.Copper: smelting, producing and classifiionMetalpediaCopper: smelting and classifiion The smelting of copper Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.
electrolytic recovery of copper from solution ezyflexi.inRapid recovery of dilute copper from a simulated Cu–SDS In this study, electrolysis experiments were conducted to evaluate the influences of pH, current density, solution mixing, SDS concentration, and copper concentration on copper recovery from a simulated dilute copperLeaching and electrochemical recovery of copper, lead and The recovery of copper, lead and tin from scrap printed circuit boards (PCBs) has been achieved using a combination of leaching, electrochemical ion exchange and electrodeposition.
Structure and Properties of Electrolytic Copper Alloys (copper) is released at the limiting diffusion current, and the rate of discharge of its ions into the alloy remains virtually unchanged compared to the separate recovery.

RECOVERY OF COPPER FROM BRONZE SCRAPanode grade copper. Abdul Basir and Rabah (2001)showed that copper recovery from scrap was favoured with the use of some additives altogether with the chemical reagents.Yadavalli and Saha (1994)recovered pure electrolytic copper (99.98%) from leaded brass scrap containing 60.02 % copper, 39.3 % zinc and 0.53% lead.Electrochemical recovery of copper from alloy scrap 1976525&ensp·&enspThe recovery of substantially pure copper in this manner permits recovery or reuse of copper by hydrometallurgical means. That is, the substantially pure copper which is recovered can be used to make copper articles, new copper alloys, substantially pure copper compounds, or any of the common commercial uses of pure copper.
Leaching and recovery of zinc and copper from brass slag The results of the effect of agitation rate on zinc and copper dissolution by 30% H 2 SO 4 with leaching time 10 min and at 35°C investigated in the range of 60–400 rpm with liquid/solid mass ratio of 5/1 are shown in Fig. 1.The presented data show that the recovery of zinc was increased from 60% at 50 rpm to around 93% at 150 rpm and the recovery of copper was kept around 9% with variousElectroplating WikipediaChineseElectroplating is a process that uses an electric current to reduce dissolved metal ions so that they form a thin coherent metal coating on an electrode.

The first known maps printed from copper plates are two Italian editions, dated 1472, by the geographer Ptolemy. Copper or bronze wire then became a very important product, being vital for the weaving industry.
