PSA Oxygen Plant For Gold Ore Oxidation Leaching

PSA Oxygen Plant For Gold Ore Oxidation Leaching

The PSA Oxygen Plant for Gold Ore Oxidation Leaching is a core oxygen supply equipment for the gold ore oxidation leaching process. Based on pressure swing adsorption (PSA) technology, it efficiently extracts oxygen with a purity of 90%-95% from the air and delivers it to the leaching system on demand. Featuring a modular design, the equipment is compatible with gold ore production lines of different scales. It enables on-site continuous oxygen supply without the need for external oxygen cylinders. Compared with traditional oxygen supply methods, it reduces energy consumption by more than 30% and has a high degree of automation, allowing real-time adjustment of oxygen concentration and supply volume to accurately match the reaction requirements of gold ore oxidation leaching (such as cyanide leaching and bioleaching). It significantly improves gold recovery rate while reducing exhaust emissions and transportation costs, making it a key equipment for green and efficient production in modern gold mines.

Description

Technical Parameters

The main role of PSA oxygen generator in gold mines

 

Accelerate Oxidation Reaction: Continuously supply oxygen to the gold ore leaching system, promote the oxidation of sulfides and iron ions in the ore, create a suitable chemical environment for gold ion dissolution, and shorten the leaching cycle.​
 

Improve Gold Recovery Rate: Stable high-concentration oxygen supply breaks the "oxygen limitation" bottleneck in the leaching reaction, enabling more sufficient dissolution of gold ions and increasing the recovery rate by 5%-15%.​
 

Optimize Process Conditions: Precisely adjust oxygen partial pressure to adapt to the leaching needs of different ore types (such as oxidized ore and sulfide ore), and avoid process fluctuations caused by unstable oxygen supply.​
 

Reduce Production Costs: On-site oxygen production eliminates the need for purchasing external oxygen cylinders, saving transportation and storage costs. With low energy consumption, it reduces costs by 20%-30% compared with traditional oxygen supply methods in long-term use.

FAQ

 

 


 

1.Can the oxygen purity of the equipment meet the leaching needs of high-sulfide gold ores?​
It can stably output oxygen with a purity of 90%-95%. For high-sulfide ore leaching that requires a purity of over 92%, customized upgrading is available to fully meet the demand.​

 

2.How long is the equipment installation cycle? Is production suspension required for installation?​
With a modular design, the installation cycle is 15-30 days. It supports "installation while production", requiring only 1-2 days for connection and commissioning, which basically does not affect production.​
 

3.What is the service life of the molecular sieve? Is the replacement cost high?​
The imported molecular sieve has a service life of 8-10 years. The replacement cost is about 10% of the total equipment price, and replacement only takes 4 hours without affecting long-term production.​
 

4.Can a connection plan with the existing leaching system be provided?​
On-site survey of the existing system can be conducted, and a complete connection plan including pipelines and control systems can be provided to ensure seamless connection without additional production line transformation.​

 

5.How many operators are required for equipment operation? Is professional training needed?​
It operates fully automatically and can be monitored by 1 person. Free on-site training is provided, and operators can master operation and basic maintenance in 2 days without the need for professional personnel.​
