Zinc Precipitation Stage Of Gold Deposition

     Metal deposition method using Zn powder (Zinc precipitation) was first introduced by Sulman and Teed (1895). Basic usage of this method is the electron affinity of zinc metal is much higher than in metals gold and silver, then gold and silver metals will sink and be replaced by a soluble zinc. The Precipitate that occurs will be shaped cement sand. Although the use of activated carbon is used widely but many are also used primarily cementation in rocks that contain lots of silver because the cementation is a process very simple and very inexpensive.
