  • What Are Commonly Used Gold Recovery Chemicals? |

    Heap leaching gold recovery process is to first crush the ore to certain particle size (15mm) and then convey it to the storage hopper, adding gold ore, lime and binder according to the specified amount, mixing them thoroughly and sending the gold ore to the disc granulator After granulation, the gold ore is piled on the nonleakage ground (dip pad) Start presoaking with lime solutionA "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold A refractory ore generally contains sulfide minerals, organicGold extraction WikipediaIn order to investigate the difference of NaCN leaching reagent and CNLITE 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 LITE Ecofriendly Gold Leaching Reagents, Gold
