Merrill–Crowe process Wikipedia

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 Merrill).

Cementation, the physical reaction CleanMetals

Cementation, the physical reaction. Cementation is a heterogeneous process in which ions are reduced to zero valence at a solid metallic interface. It is an oxydoreduction reaction which functions as an ionexchange, dissolving the sacial metal, while cementing the ionic mineral, which thus takes a metallic form by way of a metallic powder.
