How an Oxygen generator is used in manufacturing companies
Using Oxygen in industry Adding oxygen to a process enables better control of heating patterns, higher furnace efficiencies (for lower fuel consumption) and the reduction in particulate and NOx emissions. It’s used with fuel gases to enhance processes including gas welding, gas cutting, oxygen scarfing, flame cleaning, flame hardening and flame straightening. Oxygen is a raw material in many oxidation processes and it’s also used to regenerate catalysts.
How an Oxygen generator works The air we breathe is about 21% oxygen. Oxygen for industrial use is generated by separating oxygen molecules from the other molecules within a clean, dry compressed air stream. Pressure Swing Adsorption (PSA) is a simple, reliable and cost-effective technology that enables continuous, high-capacity oxygen flow at the desired level of purity. Adsorption happens when atoms, ions or molecules from a substance (compressed air in this case) adhere to a surface of an adsorbent. PSA technology isolates oxygen molecules from other molecules (nitrogen, CO2, water vapor and trace gases) to leave high purity oxygen at the outlet of the generator. The process takes place in two separate pressure vessels (tower A and tower B), each filled with a carbon molecular sieve, that switch between a separation process and a regeneration process.
Benefits of on-site production Compared to the delivery of gas bottles or tanks of oxygen, in-house generation of oxygen offers many key advantages. For example, it ensures continuous availability of oxygen, removing the risk of a production breakdown due to delivery issues or supplier shortages. It avoids the hassle of constant order processing for refills and delivery costs associated with bottled oxygen. It also eliminates the space and special handling requirements for full oxygen bottles in inventory and empty bottles awaiting pickup, refill and re-delivery.

Industrial PSA VPSA Oxygen Generator plant for mines and gold mining
Oxygen generation systems are operating in some of the world’s most remote gold mines to ensure that miners are supplied with sufficient oxygen, several cubic metres of oxygen per personnel is required every hour.
Why use Oxygen Generator for Extraction Mining?
Our oxygen generator for mining can work in any altitude, climate, or conditions, this dramatically improves safety for mining personnel but also provides oxygen for the leaching process. Mines that extract gold on an industrial scale usually use the cyanide leaching process. The gold-bearing rock is first ground to this end. A sodium cyanide solution is then allowed to seep through the ground rock. The solution is enriched with artificial oxygen for this purpose. By using oxygen to convert mineral sulfides to sulfates and processing them, gold yield can be more than doubled over standard ore gravity separation and concentration.
Why Use generators for Extraction Mining? provides custom design units for industry operation with the highest quality parts intended for extreme environments. Ideal for hot, cold and humid climates. This makes our systems ideal for mining operations with
Gold cyanidation (also known as the cyanide process or the MacArthur–Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore through conversion to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in silver extraction, usually after froth flotation.
Production of reagents for mineral processing to recover gold represents 70% of cyanide consumption globally. While other metals, such as copper, zinc, and silver, are also recovered using cyanide, gold remains the primary driver of this technology. The highly toxic nature of cyanide has led to controversy regarding its use in gold mining, with it being banned in some parts of the world. However, when used with appropriate safety measures, cyanide can be safely employed in gold extraction processes. One critical factor in its safe use is maintaining an alkaline pH level above 10.5, which is typically controlled using lime in industrial-scale operations. Lime plays an essential role in gold processing, ensuring that the pH remains at the correct level to mitigate risks associated with cyanide use.

PSA Oxygen Principles
The principles of Pressure Swing Adsorption (PSA) oxygen generator are adsorption and desorption.
Each gas has a characteristic adsorption rate that when adsorbed by Zeolite Molecular Sieve (ZMS). ZMS has large
surface area containing a mass volume of micro pores and passageways. Nitrogen has a higher adsorption rate than
oxygen when delivered to the ZMS bed after pressurized. When compressed air enters ZMS, oxygen molecules are able to
pass through this large surface, and nitrogen molecules are adsorbed to the surface area.
Adsorption and desorption/diffusion are the general principles of the PSA system since each gas has a characteristic
adsorption rate that is a function of its ability to be adsorbed by a molecular sieve. The adsorption process can produce
a range of gas with purities more than 90% oxygen.
The different capacities that ZMS adsorbing O 2 molecule and N 2 molecule can be shown by the adsorption balance
vessels filled with ZMS to produce a continuous stream of oxygen.
During depressurization, the oxygen of lower purity than required is transferred to another vessel first, which is called
pressure equalization. Pressure equalization donates to higher efficiency and less energy consumption. Then the adsorption and desorption/regeneration processes switch in the two adsorption towers.
