2019-4-15  The cyanidation process is still the dominant technique for gold ore treatment. In this study, the potential use of the guanidine extractant LIX 7950 for recovering silver and gold from alkaline cyanide solution was investigated. The results indicate that LIX 7950 can effectively and efficiently extract silver and gold from their cyanide solution.

What is Gold Cyanidation? (with picture) wiseGEEK

2021-1-19  Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.
