In order to ensure good leaching kinetics and high overall gold recovery, it is . always necessary to add cyanide during leaching than will be consumed in the leaching process. This excess cyanide reports to the tailings as uncomplexed or free cyanide, and it is often possible to recycle a portion of this cyanide at minimal cost.

Oct 20, 2014 Liberation Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or usually the ore is crushed and ground to a size at which the surface of the gold is exposed – i.e. the gold is liberated.

Jul 11, 2018 Heap leaching occurs after the mining and crushing of low-grade ores, usually in an opencast mine. High-grade ores and ores not amenable to cyanide leaching at coarse particle sizes require further processing to recover the gold values. These processing methods can include further grinding, concentration, pressure oxidation, and roasting, which.
