Lihir processing plant is designed to process 3.6 Mtpa of ore containing 7.2% sulphide sulphur at a gold grade of up to 13 g/t and a plant availability of 86%. The instantaneous design feed rate is 375 t/h of ore containing 27 t of sulphide sulphur.
Bio-oxidation: Bio-oxidation uses sulfur consuming bacteria in a water solution to remove sulfur. Pressure oxidation: Utilizes oxygen and heat under pressure in a liquid medium, to effect oxidation of sulfur by way of a controlled chemical reaction. High pressure autoclaves are used for the reactors. Reactor operation is under
Autoclave and Pressure Oxidation Mining and Minera. 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

XSM stone crushing machine project-pressure oxidation plants for gold production worldwide
"Pressure oxidation was selected as the most feasible processing technology for double refractory ores. It is able to achieve gold recoveries of 96% by utilising high temperatures, elevated pressure and oxygen to recover encapsulated gold, while conventional cyanidation methods would result in sub-optimal recovery rates of 20-40%.

Sep 22, 2013· Outotec provides the mining and metallurgical industry with advanced solutions for processing a variety of gold ore types ranging from free-milling ores to refractory gold .
Your gold concentrate will afterwards undergo ultrafine grind and go for the cheapest oxidation there is ie: Atmospheric or Low Pressure Oxidation before going to classic CIL. This last more costly option is commonly known as POX or High Pressure Oxidation for the most difficult refractory gold ores.
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.

In gold production, supplies valve solutions for processing plants using carbon-in-leach (CIL), carbon-in-pulp (CIP) or carbon-in-column (CIC) circuits. Our valves can handle the tough process environment created by autoclave pressure oxidation (POX).
The project consisted of a conventional open-pit (24,000 tonnes per day) mining operation, with a pressure oxidation / carbon-in-leach (CIL) plant to recover gold and silver, as well as a copper sulfide precipitation circuit to recover copper. Fluor staff peaked at 380 in March 2011, and contractors peaked at 7,800 for 3 months in April 2011.
The Russian gold miner said its substantial investment in a pressure oxidation hub, just one of two in the country, is paying off. "The commissioning of the POX plant has enabled Petropavlovsk to unlock the potential of our refractory ore reserves at Malomir, which has led to a near-doubling of gold production from a year ago," said Pavel ...
The Porgera gold mine is located in Enga Province, about 600km north west of Port Moresby. The mine is operated by a joint venture between Placer Dome (75%), Orogen Minerals Ltd (20%) and Mineral Resources Porgera Pty. Ltd (5%), the latter two representing the state of PNG and local landowners. In ...
pressure oxidation and resin in pulp have been demonstrated in pilot plants. The results of the hydrometallurgical investigations are presented here. INTRODUCTION The South African gold and uranium producer, Gold Fields Mining SA (Pty) Limited, is developing a flowsheet to treat historic tailings as well as current arisings from their
Uranium Nickel Gold Copper Cobalt Rare earths Zinc High Pressure Acid Leach (HPAL) and Pressure Oxidation (POX) testing services provide a unique opportunity to evaluate and optimise the most economically viable process routes for the recovery of most metals such as nickel from lateritic ores and gold from refractory ores.
