Cementation (metallurgy)Wikipedia

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.
