WebGold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. [1] WebThe objective of heap leach construction is to build a stable, porous heap that allows an even downward percolation of cyanide solution (Herzog 1990). Heaps are commonly …
