HIGH TEMPERATURE OXIDATION OF METALS AND ALLOYS 327 In the next Figures (24) three relatively simple possibilities for forming oxide layers are selected.
Effect of Chloride Concentration on Gold Recovery in Pressure Oxidation Process specializing in the design of highpressure metals recovery plants.
This article describes a novel process for the recovery of platinum lost in ammonia oxidation plants for the manufacture of nitric acid. The process, based on the finding that the platinum lost is in vapour form, is particularly suitable for medium and high pressure plants in which the present methods of recovery are relatively inefficient.

Pressure Oxidation is a process for extracting gold from refractory ore. The most common refractory ores are pyrite and arsenopyrite, which are sulfide ores that trap the gold within them. Refractory ores require pretreatment before the gold can be adequately extracted.
Pressure Oxidation (POX) is a process used to extract gold, copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes

Pressure oxidation (POX), high pressure oxidation (HiPOX) and ACTIVOX autoclave leaching are viable industrystandard technologies used to recover gold and other accessory metals. The process is particularly well suited for treating refractory gold ores, which give low recovery when directly leached with cyanide.

High Pressure Acid Leach amp; Pressure Oxidation High Pressure Acid Leach ore types such as nickel laterites and refractory gold ores.
Pressure oxidation was developed for processing refractory ores where gold is occluded in the sulfide minerals, typically pyrite or arsenopyrite. Oxidation of the sulfides at elevated temperatures and pressures liberates the gold, allowing it to be economically recovered by conventional circuits.
