BACKGROUND REPORT SECONDARY COPPER

2021-6-25  Castingof alloyed or refined copper products is the final step used by the secondary copperindustry in the recovery of copper from scrap material. The molten metal is poured into molds fromladles or small pots serving as surge hoppers and flow regulators. The resulting products includeshot, wirebar, anodes, cathodes, ingots, or other cast shapes.

COPPER Copper production - TU Delft

2008-12-16  Surface treatment of copper is a group of operations for surface protection or surface refinement. These include mechanical, electrical, or electrochemical handling, e.g., polishing, matte finishing, pickling by dilute sulfuric or nitric acid, metal coating or electroplating (with nickel, nickel and chromium, tin, silver, gold, or platinum metals), lacquering or coating with synthetic plastics (mainly for

Recovery of Precious and Secondary Metals from ...

2016-3-4  MOSTmodern 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. In the earlier years this was done for the sole purpose of promptly recovering in marketable form the silver and gold contained in the slime. Later, improvements in refining methods made possible the recovery of the more precious metals such as platinum, palladium, osmium and iridium, and in recent years, due largely to an increasing market, many secondaries plants have undertaken the commercial production of selenium and tellurium. The complete up-to-date second- aries plant, or silver refinery
