Smelting of low-grade copper scrap begins with melting in either a blast or a rotary furnace, resulting in slag and impure copper. 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 AMES Copper Group process is considered a secondary copper refinery and consists of a pyrometallurgical process to transform scrap copper into copper anodes with over 99.7% pure copper. ... Copper scrap is sorted and sampled, melted in an appropriate furnace, refined, and cast into anodes. Contact Us; PHONE: (980) 552-3530. 125 Old …
The smelter separates precious metals in a copper bullion, from mostly all other metals, concentrated in a lead slag, further treated at the Base Metals Operations. After leaching out the copper in the leaching and electrowinning plant, the precious metals are collected in a residue that is further refined at the precious metals refinery.
