A carbonaceous gold refractory mineral was studied. The characterization of the sample was carried out by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), FTIR, Leco SC and oxidative leaching. The chemical analysis presents 9.83 g/t Au, the mineralogical 24.03% of fixed carbon (Leco SC). The Preg-robbing tests show that the mineral adsorbs 94.34% of gold from the solution in 30 minutes and the recovery of gold in the conventional cyanidation test was 3.36% in 24 hours with granulometry 80% through mesh No 200, this reveals the high degree of refractoriness of the mineral. The results of oxidative leaching-roasting and direct roasting tests in conjunction with the mineralogical analysis of the mineral suggest that refractory gold is mainly associated with carbonaceous material. The oxidative process with HCl and cyanidation only allows the recovery of 8.15% of gold, generated by the liberation of gold from carbonates; while, through the oxidative process with HNO3 and cyanidation, the recovery was even lower than only 2.20% of gold. The residues of the oxidative process were subjected to roasting at 800°C and a 25.42% recovery of gold was obtained. This low recovery was probably due to the high roasting temperature that produced a mineralogical transformation, where the mineral formed Ca6O19Si6 and Ca2MgO7Si2 could re-trap the released gold, reducing its recovery during cyanidation. The results of the direct roasting of the mineral at 500°C, 600°C and 700°C, show that the mineral presents 22.83 ± 0.56% loss of mass at 700°C, very close to the value of fixed carbon and at this temperature it was obtained the highest gold recovery of 91.06 ± 0.31%, which confirms that gold is associated with carbonaceous material.
