Description

Technical Parameters

Write down why psa oxygen generator is used in gold mining?

●Efficient Process Adaptation: Adopts pressure swing adsorption technology to produce oxygen with 90%-95% purity, precisely meeting the needs of processes like cyanide leaching. It increases gold recovery rates by 2-5 times and shortens leaching time by over 50%.

●Significant Cost Reduction: Eliminates liquid oxygen transportation and storage needs, cutting oxygen procurement costs by 70%. With a compact structure and low initial & operational energy consumption, it meets gold mines' economic requirements.

●Stability & Disturbance Resistance: Enables on-site continuous oxygen generation, avoiding production disruptions from liquid oxygen logistics delays. Dust-proof and adaptable to temperature/humidity variations, it fits harsh mining environments and ensures uninterrupted production.

●Enhanced Safety: Achieves normal-temperature oxygen generation without high-pressure cryogenic storage, eliminating liquid oxygen leakage and explosion risks. It can supply breathing oxygen underground, reducing hazards from harmful gases.

Gold mining oxygen generator Core Technology

Air Compression

Air is first filtered to remove impurities and then compressed by a compressor. This increases the air pressure, providing the necessary driving force for the subsequent oxygen-nitrogen separation process.

Adsorption Separation

The compressed air enters an adsorption tower filled with a molecular sieve. The molecular sieve has the property of preferentially adsorbing nitrogen while allowing oxygen to pass through. As a result, high-purity oxygen is obtained on the other side of the tower.

Desorption Regeneration

When the molecular sieve in the adsorption tower becomes saturated with nitrogen, the pressure is reduced. This causes the nitrogen to be released from the molecular sieve, completing its regeneration. The regenerated molecular sieve can then be reused for the next adsorption cycle.

Flexible Oxygen Supply

It can be customized according to the actual oxygen demand of the gold mine. The oxygen production capacity and purity can be adjusted as needed, ensuring an optimal supply of oxygen for different mining processes.

FAQ

1.What oxygen purity do gold mining oxygen generators produce, and why does it matter?
Typically 90%-95%. This purity boosts cyanidation leaching and pressure oxidation - far more effective than ambient air .

2.How does on-site generation compare to liquid oxygen in cost and supply?
Costs: Cuts procurement by up to 70% + low energy use . Supply: Avoids delays via on-demand, continuous production, no shutdowns from shortages.

3.What are common malfunctions, and how to fix them?
Purity drop: Replace filters or faulty molecular sieves; check leaks.
Low pressure: Fix leaks, match capacity to demand, clear blocked pipes.
Shutdowns: Check power (voltage/phase) or calibrate sensors.

4.What regular maintenance is needed, and why?
Replace air filters (3-6 months): Protects molecular sieves (key for purity).
Calibrate purity sensors (6 months): Ensures 90%-95% output.
Annual mechanical checks: Lubricate/replace parts (compressors/valves) to avoid downtime.This maintains performance and extends equipment life.
