Apr 17, 1979· Some of the arsenic remaining in solution is precipitated with the copper in the cementation stage. Copper is generally precipitated first, however, so that the amount of arsenic precipitated with the copper can be held at a very low level by holding copper recovery in the cementation stage to about 95%.
Recovery of copper and/or other metal values from pregnant, highly dilute liquors and conversion of the barren liquor to a suitable lixiviant; for recovery of copper or other metal values from leaching systems, such as acid treatment of mine waste dumps, vat or heap leaching and insitu mining as part of an overall copper recovery process.
Copper is traditionally known as the "red" metal after its natural color. However, it is also known as a "green" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look.

Copper Cementation Cone In the search for lower cost methods of recovering copper, the use of sponge iron or particulate iron (as distinguished from iron powder used in powder metallurgy) as precipitants in place of tin cans, detinned scrap iron, or scrap iron is an intriguing possibility.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Kennecott, also known as Kennicott and Kennecott Mines, is an abandoned mining camp in the Valdez-Cordova Census Area in the U.S. state of Alaska that was the center of activity for several copper mines. It is located beside the Kennicott Glacier, northeast of Valdez, inside Wrangell-St. Elias National Park and Preserve.The camp and mines are now a National Historic Landmark District ...
Jan 11, 1972· The copper ions are customarily placed in solution by running a weakly acid leach solution, containing ferric and sulfate ions, through a mine dump or by otherwise contacting a copper-bearing material with the solution. The leach solution, pregnant with copper, is brought into contact with metallic iron for precipitating "cement" copper.

The conversion of copper to cement copper was 67.7 percent, and the conversion of the ferric iron to ferrous iron was 71.6 percent. Thus, it appears that reactions 1 and 2 proceed simultaneously and at essentially the same rate when copper and Fe+3 ions are present in about the same concentrations. Cement Copper Purity
