Acid Copper and Cyanide Copper coatings Hohman Plating
Acid copper is used for heavier coatings where a level deposit is desired. It cannot be applied directly over steel or zinc (due to the high sulfuric acid content), unless alkaline based copper is used as an initial layer to provide a barrier from the acid. Acid copper is softer, and brighter than cyanide copper....
Primary Copper Smelting
Primary Copper Smelting General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total ... copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions. Depending upon the chemicals used, some minerals...

Coppersilver ionization as a disinfectant
Coppersilver ionization can deactivate Legionella bacteria and other microorganisms in slowrunning water and still water. Legionella bacteria are very susceptive to coppersilver ionization. Coppersilver ionization also takes care of bio film. Copper remains within the bio film, causing a residual effect....

The Facts on Copper Recycling
Copper is a nonferrous metal, and valued as the best nonprecious metal conductor of only metal with better conductive properties is silver. Copper holds as much as 90 percent of new copper value, and as such it is one of the basic targets for many scrap metal are some other basic facts about copper and copper recycling:...
Brass Finishes for Various Metals – Electroplating – EPi
Brass is an alloy of copper and zinc. It is used primarily in decorative finishes, but brass plating also has valuable engineering uses. Achieving bright brass finishes and finishes that will be buffed, burnished, antiqued, or oxidized requires different finishing processes. For Industrial Use....
