Comparison with Sodium Cyanide

In order to investigate the difference of NaCN leaching reagent and CNFREE leaching reagent in the leaching effect on gold ore, we choose six kind of gold ore samples which are oxidized gold ore in Sultan Kush, oxidized gold ore in Tanzania , oxidized ore and mixed ore of gold mine in Tanzania , oxidized gold ore gravity separation tailings in Tanzania (T5) for leaching comparison test.
