Autoclave feed is pumped through three closed stainless steel carbonate reaction tanks in series, the concentrate being mixed with recycled oxidised slurry. The autoclaves operate at 1,725kPa pressure and 197°C, producing feed for the leaching and CIP circuits. Combined leach and CIP recovery is 90–95% of the contained gold.

In refractory gold processing, efficient carbonate removal, conditioning, and neutralization steps are handled with the modular Outotec OKTOP® reactor packages combining process, automation, and equipment know-how. If chloride enters the autoclave, it is efficiently washed out in the Outotec Larox® filtration plant with minimum water consumption.
The process is particularly well suited for treating refractory gold ores, which give low recovery when directly leached with cyanide. SGS is a world leader in batch and pilot plant testing and flowsheet development for pressure oxidation processing. We have the expertise and equipment inventory to test your ore in our state-of-the-art facilities.
High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodies. The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore.
Mar 10, 2014· "We would otherwise be challenged to keep all the folks in the autoclave circuit employed," Schack says. "With the new process we essentially will be able to keep those facilities going well past 2025." The change to the autoclaves also allows Barrick to bring millions of gold ounces forward in Goldstrike's production schedule.
