Lime is added to the process in order to have a pH near to 10-11. Video of cyanide gold process production line.For gold extraction the strength of cyanide solution ranges from 0.01 to 0.05%. 3 Recover gold from the solution with zinc powder by precipitation. 2 Separate solid from the clear solution. 1 Contact finely ground ore with the solution containing cyanide. Cyanidation: It is one of the main methods of gold extracting process.
