Abstract:

 This study focuses on improving gold recovery from ore samples from the Uşak Kışladağ Gold Mine, specifically those sized -180 mm. The ore was crushed below 2.36 mm and mixed with locally abundant alkaline limestone to enhance permeability and gold dissolution efficiency. Permeability tests were conducted on the -180 mm and -2.360 mm sized ores, with results of 1.28 x 10³ cms and 0.62 x 10³ cms, respectively. Additionally, the -2.36 mm ore was mixed with various limestone sizes -1810 mm, -105 mm, and -50 mm at ratios of 15, 50, 100, 150, and 200. The best permeability results were observed with the -2.360 mm ore and -105 mm limestone mixture. Consequently, leaching experiments were conducted with 1:1 and 1.5:1 ratio of the -2.360 mm sample mixed with limestone, resulting in gold dissolution efficiencies of 63 and 53, respectively. Furthermore, bottle-roll tests were performed on -2.360 mm and -750 μm samples for 48 hours, with gold recoveries of 64 and 83, respectively.
