Firstly, XRF, XRD and Thin-Section studies were performed on representative sample. Then, the ore was crushed and ground by jaw, cone crushers and ring mill, respectively. Particle size of the product was 75 µm based d80. Again, the product was subjected to grinding process by vertical wet stirred ball mill and final ground product was used as leach feed material. The leach feed material has about d80= 20 µm and d50=6.02 µm particle size. Leaching study was performed by using quicklime quantity, solid ratio, temperature, cyanide concentration and leaching time parameters. The final experiments show that the recovery of Au and Ag was 91.92% and 82.15% under optimum leach conditions.trinfo:eu-repo/semantics/openAccessAltın CevheriDik Karıştırmalı Bilyeli DeğirmenMekanik AktivasyonMetal Kazanma VerimiGold OreVertical Stirred Ball MillMechanical ActivationRecoveryMaster Thesis386127
