Values greater than 0.25% S“ typically result in poorer gold recoveries in the C1L circuit. Free-acid levels in the autoclave discharge are a function of S2 and CO2- in the autoclave feed, but normally range from 10 to 25 g/L H2S04. The slurry discharges from the autoclave and passes through a series of pressure …

Kinetic factors are particularly important in the acid pressure oxidation of sulfides, with oxidation products varying according to the temperatures and pH value of the system (Mackiw et al., 1966).This is illustrated in Fig. 1, which shows that although metal sulfides are oxidized completely to sulfates under acidic conditions at temperatures above 175°C, at lower temperatures elemental ...
