The characterization studies showed that the tailings sample mainly formed from silicate minerals and the sample contained 77.10% SiO2, 8.08% Al2O3, 5.76% Fe2O3, 1.67% CaO, 1.10% Na2O, 0.97% K2O and 4.366% loss on ignition. The results of leaching studies indicated that gold dissolution decreases with in- creasing solid ratio. Furthermore, the gold leaching positively influenced by the NaCN concentration in the range of 0.05-0.50 g/L and by the pH in the range of 10.00-10.30. However, at pH values greater than 10.30, the gold leaching decreased. The temperature and stirring speed also affected gold leaching in different ways. The leaching studies revealed that it is very simple to apply the cyanide leaching to the tailings and a gold recovery value of 87.5% could easily be reached. Commercially, this study reported an economically feasible process for gold recovery from an artisanal small-scale gold mining tailings in Arbaat.Basılı+Elektronikeninfo:eu-repo/semantics/openAccessAgitation LeachingMühendislik Temel Alanı>Maden Mühendisliği>Kimyasal-Biyolojik Kazanma Teknikleri ve Cevher Hazırlama>Metalik MadenlerArtisanal Small-Scale Gold MiningCyanidation.Gold Tailings.Article10.30797/madencilik.1416245
