Summary of Gold Cyanidation

First, gold in the gold-bearing ore reacts with cyanide to form a complex into the solution, and then the gold is removed from the solution to metal by a displacement reaction using reactive metal such as zinc. The reaction equation is: 4Au+8NaCN+2H2O+O2=4Na [Au (CN) 2] +4NaOH 2 Na [Au (CN) 2] +Zn=2Au+Na2 [Zn (CN) 4] 2. Gold Cyanidation Flow
