this usually means sacrificing some gold recovery. The lowest cost gold is normally produced by open pit mining with minimal crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to 95-99% by grinding to fairly fine particle

ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carbon-in-pulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.

The strip is also more complete but with plant carbon you are looking at 30 versus 50ppm residual gold, time and thus cost is the major factor for use. All pre-leaches and steel wool digestions are done with HCl, apart from getting a better result the cost is way cheaper.
