refining copper from brass

ASARCO » Refining

Scrap copper comes from manufacturers of all sorts of copper and brass products. The copper is melted and cast into anodes and refined just like ‘new’ copper from the mines and smelters. That other 1% is valuable stuff! Refining removes the impurities from the copper, but those impurities are valuable elements like silver; gold; platinum

Copper Refining - an overview ScienceDirect Topics

In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.

Metal recycling opens up the metal reserves found in products and therefore makes a considerable contribution to the supply of copper and other metals. Copper recycling fulfills the criteria for sustainable development and is the foundation of modern recycling management.

BACKGROUND REPORT SECONDARY COPPER SMELTING,

If a blast furnace is used, this copper is charged to a converter, where the purity is increased to about 80 to 90 percent, and then to a reverberatory furnace, where copper of about 99 percent purity is achieved. The final step is known as fire-refining. In these pyrometallurgical processes, flux is added to the copper and air is blown upward
