Gold Mining •Two basic processes including mineral processing and gold extraction by cyanide leaching is taken place in a mining area. •Tailing from gold extraction processes and its storage method in tailing dam is evaluated. •A stochastic model is applied for designation of the tailing as hazardous waste and appropriate treatment technology and
Gold Extraction Methods Although new process are being proposed on a regular basis, there have in fact been no dramatic changes in the metallurgical techniques for gold extraction since the introduction of the cyanide process (cyanide leaching or cyanidation) by McArthur and Forrester in .
The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation.

Issues of gold extraction using cyanide: Cyanide is toxic to animal and plant life and may cause death if exposed to high enough doses. Free cyanide is cyanide ion (CN-) and hydrogen cyanide (HCN) which is often gaseous as it is volatile. Free cyanide causes cellular asphyxiation. The process: The ore is ground and crushed to make a slurry
Gold 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.
Despite of being the most common hydrometallurgical process for extraction of gold from ores and concentrates, cyanide leaching is blamed for its hazardous impact on environment and human health. These concerns have given a rise for alternative cyanide-free technologies, such as .
