This process works by exposing the surface of the finely crushed ore to the cyanide salt solution. Once exposed to the gold, the solution binds with ions in the gold that allows them to separate out into solution and then be screened for collection. It is well-known that the introduction of more oxygen speeds up the leaching process but it is ...
