leaching circuits, even when the ore is finely ground. The cause of low gold recoveries can be either through the presence of naturally occurring ‘preg robbing’ carbonaceous materials or gold physically ‘locked’ in sulphide minerals. The majority of gold ores are classified refractory because the gold mineralogy is contained in sulphides.

roaster gas. Our circulating fluidized bed technology enables the necessary fine control over these parameters. To avoid losses in the leaching plant, it is recommended that whole ores are treated with a gold-roasting step. Due to the low specific heat value of whole ore, it is generally necessary to add fuel to the reactor.

Roasting of Gold Ore in the Circulating Fluidized-Bed Technology
2016.1.1 Abstract. Gold roasting is a process, applicable to refractory ores and concentrates that contain sulfide sulfur, organic carbon, and potentially arsenic. Removal of these compounds is necessary to achieve high gold recovery (>90%) during cyanide leaching. Gold roasting is typically a metallurgical fluidized bed process.

Magnetic Recovery of Gold-Bearing Iron Oxides at Barrick
Gold is often present in solid solution with pyrite in the Carlin Trend. The presence of organic carbon along with gold hosted in sulfide, referred to as double refractory ore, requires that ore with high carbon-in-leach (CIL) preg-robbing potential and poor leach recovery is routed to a roaster. During roasting, the pyrite is oxidised to (ideally) form
