Cementation is a type of precipitation, a heterogeneous process in which ions are reduced to zero valence at a solid metallic interface. The process is often used to refine leach solutions.. Cementation of copper is a common example. Copper ions in solution, often from an ore leaching process, are precipitated out of solution in the presence of solid iron. ...
A kinetic investigation of copper cementation in a revolving drum was undertaken by the Bureau of Mines to explore the effects of a porous copper deposit attached to the iron surface and a fluidized slurry of copper particles surrounding the iron precipitant.

Iron Mountain Mines, Inc. insitu remediation summary History of copper cementation and bioleaching Cementation of copper began with the discovery of copper and the beginning of copper mining at Iron Mountain around 1896. By 1908 the State Geologist reported that the operation was so extensive that a building was being constructed over and ...
Cementation of copper is a common example. Copper ions in solution, often from an ore leaching process, are precipitated out of solution in the presence of solid iron . The iron oxidizes, and the copper ions are reduced through the transfer of electrons.
In metalwork: Renaissance to modern .by a process known as cementation, in which water containing copper forms a deposit on iron. Production was limited to three places in the county of Sohl in Hungary.
Cementation is an effective process that meets the requirements of process cleanliness. The performance of the cementation reaction is dictated by a number of variables. In this study, the effects of various parameters on the yields of copperiron cementation (wire and powder) were investigated.
The majority of employees already working for Nevada Copper or Cementation are locals. ... "So the mine could go for a long, long time as it transitions from copper to iron." ...
Cementation can be used on lowgrade copper ores and even on copper in wastewater. Cons: Miners need enough scrap iron to make cementation work, and scrap iron is sometimes unavailable.
