gold_cyanidation

gold cyanidation (also known as the cyanide process or the macarthur-forrest process) is a metallurgical technique for extracting gold from low-grade ore by converting the gold to water soluble aurocyanide metallic complex ions. it is the most commonly used process for gold extraction.due to the highly poisonous nature of cyanide the process is highly controversial.

what is gold cyanidation? (with picture)

nov 02 2019· gold cyanidation also called cyanide leaching is a process used to extract gold from raw ore taken from the ground. it uses cyanide to dissolve the gold within the rock which itself is not soluble in cyanide. the gold is then drawn out in a liquid form that can be treated to remove the cyanide.

cyanide leaching of gold

once the gold has been dissolved in the cyanide and the ore body has been reasonably depleted of its gold there are two main processes for recovering the gold from the pregnant cyanide solution. one is the merrill-crowe zinc precipitation process and the other is the adsorption of the gold …

cyanide leaching | mining | sgs

cyanide leaching has been the industry standard for gold processing for more than 100 years. during the cyanide leach process a cyanide solution or lixiviant is percolated through ore contained in vats columns or heaps. gold is dissolved by the cyanide and then removed from the heap or columns.
