Solution for precipitating gold from HAuCl 4 solution. A discussion started in 2005 but continuing through 2018. 2005. Q. Respected Sir, My technical problem is how to precipitate gold from HAuCl 4 solution. We recover gold from Filings, Setting, Waste water, Consumables used in production, Emery papers, and sweeps from the production floors.
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 .
was used to remove gold from a cyanide solution by using zinc dust to precipitate gold from its solution. Carbon adsorption is increasing using in newer plants for gold recovery. Carbon in Pulp (CIP) technique involves contacting the leached pulp with granular carbon in a series of agitating tanks with a sufficient retention time.
The Merrill–Crowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores. It is an improvement of the MacArthurForrest process, where an additional vacuum is managed to remove air in the solution (invention of Crowe), and zinc dust is used instead of zinc shavings (improvement of ...

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. ...

gold . INTRODUCTION Zincdust cementation for gold and silver recovery, also wellknown as the MerillCrove process is the one of the most common contact – reducing processes in hydrometallurgy (Nicol et al., 1979). Cementation is the electrochemical precipitation of one metal by using another metal as a reducing agent.
