copper recovery systems. The design of these specific abatement/resource recovery systems assumes: 1) reduction of the contaminant content of an effluent to a level meeting regulatory standards, and 2) recovery of the contaminant in concentrated form suitable for reuse or sale. Electrolytic extraction of metal is one method which
Copper anode slimes, produced from copper electrolytic refining, are important industrial by-products containing several valuable metals, particularly silver and gold. This article provides a comprehensive overview of the development of the extraction processes for recovering silver and gold from conventional copper anode slimes.
An example where copper is further purified is at the Asarco electrolytic plant in Amarillo, Texas. The 99% pure copper from the anode furnace is cast into 750-pound, 3-inch thick, rectangular slabs called anodes. The final step is a process called electrorefining.

The blister copper is then dissolved in H 2 SO 4, which can be made from the gases evolved in roasting and reduction, and the solution electrolyzed to produce cathodes of pure electrolytic copper. Gold and silver are usually recovered from the electrolysis sludge, and help the economics of the process.

Recovery of Precious and Secondary Metals from Electrolytic Copper Refining (New York Meeting, February. 1934) MOST modern electrolytic copper refineries have found it expedient to build and operate a complete secondaries plant for the treatment of the electrolytic slime accumulated in the cells during the corrosion of the copper anodes.
anode 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.

Casting of alloyed or refined copper products is the final step used by the secondary copper industry in the recovery of copper from scrap material. The molten metal is poured into molds from ladles or small pots serving as surge hoppers and flow regulators. The resulting products include shot, wirebar, anodes, cathodes, ingots, or other cast ...
Copper sheets are produced by somewhat similar methods of manufacture. In the United States the majority of copper sheets are made from electrolytic copper, but in Europe fire-refined copper is used frequently in the manufacture of sheets and plates. Brass. Brass is an alloy consisting mainly if not exclusively of copper and zinc. The brasses ...
Electrolytic reduction cleaning of copper-alloyed objects, such as brass and bronze, is often avoided because it removes any aesthetically pleasing patina and may change the color by plating copper from the reduced corrosion compounds onto the surface of the alloyed metal.

The anodes and cathodes are connected to the + and - current lines respectively. ... Removal and recovery of copper, usually by electrowinning in stage-1 "liberator ...
copper and zinc from commercial brass by an electrolytic method. Such a method would produce metals which would be equivalent to metals in purity. Both Barker and Swank found that such a recovery was possible with brasses containing only copper and zinc but that very small amounts of lead would interfere with the dis-solution of the anode.
