Heap leaching is a lowcost technology used in industrial mining to recover precious metals such as gold and uranium, along with several other highly sought after metals like copper, from their primary resources (ores and minerals). For many decades, there has been a growing demand for heap leaching due to its environmental benefits. Heap leaching provides mining operators with a benign ...
· The artisanal and smallscale gold mining (ASGM) sector in Burkina Faso increasingly employs cyanide leaching to exploit the natural resource gold. The longterm consequences of chronic cyanide exposure in humans have yet to be fully elucidated.

cyanide gold leaching equipment. Gold cyanidation Wikipedia. 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 is the most commonly used leaching process for gold extraction..
The consumption of cyanide during processing operations is a major economic cost in the extraction of gold from its ores, while the discharge of cyanide wastes may result in significant environmental pollution. Many factors influence the levels of consumption and discharge of cyanide, including ore mineralogy and lixiviant solution chemistry.
