12.3 Primary Copper Smelting
www3.epa.govthe cathode. As the copper anode dissolves, metallic impurities precipitate and form a sludge. Cathode copper, 99.95 to 99.96 percent pure, is then cast into bars, ingots, or slabs. 12.3.3 Emissions And Controls Emissions from primary copper smelters are principally particulate matter and sulfur oxides (SOx). Emissions are generated from the ...
Copper-nickel Welding and Fabrication
www.copper.orgCopper-nickels can be welded by most standard processes. The core of this book is welding and fabrication. General engineering properties, corrosion and biofouling resistance and applications are included only where they influence decisions on fabrication. It provides an informed understanding of the two primary copper-nickel alloys, to allow good
