On-Site Oxygen Generator Applications For Mining

1. The oxygen generator uses pressure swing adsorption (PSA) technology to produce oxygen. How long is the service life of its molecular sieve? How often does it need to be replaced?
The service life of molecular sieves is usually affected by many factors, such as air quality, frequency of use, operating pressure, etc. Under normal circumstances, in a normal gold mine production environment, if properly maintained, the molecular sieve can be used for 3-5 years. However, we recommend that its performance be tested regularly, and whether it needs to be replaced based on the test results and the operating status of the equipment. A comprehensive assessment may be conducted once a year. If it is found that the oxygen production efficiency has dropped significantly or the oxygen purity is not up to standard, it is necessary to consider replacing the molecular sieve in advance.
 

2. In the gold mine cyanide leaching process, how to ensure that oxygen fully reacts with cyanide and gold ore?
The delivery system of the oxygen generator will accurately control the flow and pressure of oxygen and evenly distribute the oxygen to the cyanide leaching tank. At the same time, the leaching tank will be equipped with an efficient stirring device to fully mix and contact oxygen, cyanide and gold ore particles through stirring to create good reaction kinetic conditions. In addition, our system will monitor the reaction process in real time, and adjust the oxygen supply and stirring intensity and other parameters in time according to the monitored reaction conditions, such as changes in gold ion concentration, to ensure that the reaction is fully carried out.
 

3. What are the requirements for ambient temperature and humidity when the oxygen generator is operating on-site in the gold mine? What if the environmental conditions are bad?

Oxygen generators can generally operate within a wide range of ambient temperature (such as -10°C to 40°C) and relative humidity (not higher than 90%). However, if the ambient temperature is too high or too low, and the humidity is too high, it may affect the performance and life of the equipment. For high-temperature environments, we can equip cooling devices to reduce the temperature of the equipment; in cold areas, add heating and insulation facilities. For high-humidity environments, strengthen air pretreatment, such as adding dehumidification equipment, to ensure that the air entering the oxygen generator is dry, ensure stable operation of the equipment, and meet the production needs of gold mines.
 

4. If the oxygen generator fails during operation, what emergency measures are there to ensure that gold mine production is not greatly affected?
Oxygen generators are usually equipped with redundant systems and fault alarm devices. Once a fault occurs, the redundant system can be activated immediately to continue to provide partial oxygen supply and maintain the operation of key production links. At the same time, the alarm device will promptly notify the operator, and our professional maintenance team will respond quickly and take appropriate measures according to the type of fault, such as quickly replacing the faulty parts. In addition, the gold mine can reserve a certain amount of oxygen cylinders in advance as an emergency backup oxygen source to supplement the oxygen gap during the maintenance of the oxygen generator and minimize the impact on production.
