issues with gold processing flotation

Gold cyanidation Wikipedia

Gold cyanidation is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction. Depending on the ore, it is sometimes further concentrated by froth flotation or by centrifugal (gravity)
