The autoclaves operate at 1,725kPa pressure and 197°C to oxidize the pyrite (iron sulphide) into hematite (iron oxide) producing feed for the CIL circuits which recovers up …
Oxidation in autoclaves at high pressure and temperature produces a residue that contains the gold in recoverable form. Pilot plant treatment of the autoclave residue is described, …

Abstract. A significant portion of the gold in the Porgera orebody is highly refractory, being intimately associated with pyrite in submicroscopic form. Acid pressure …
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 …
The Anawe processing plant consists of a gold bearing pyrite flotation circuit, 4x autoclaves processing flotation concentrate and a Leach-CIP circuit. This paper describes a range …
Aujourd'hui, parmi les techniques d'extraction modernes de l'Or, on peut différencier 3 grandes techniques: La cyanuration est une méthode basée sur la solubilité de l'Or. Après le concassage de minerais, on l'immerge …
This paper describes the start-up of the pressure oxidation circuit which is designed to treat up to 1200 t/d of low-grade pyrite concentrate. The circuit principally …
