The Use of Ozone Gas in the Mining Industry: Sustainable, Efficient, and Safe Solutions | OCS Ozon

The mining industry faces significant challenges such as high water consumption, intensive chemical use, complex ore preparation processes, and increasingly strict environmental regulations. Ozone gas (O₃) has emerged as a powerful solution that enhances operational efficiency while reducing environmental impact, thanks to its strong oxidation capability.

At OCS Ozon, we provide industrial ozone systems designed to help mining operations achieve sustainable, economical, and safe processes.

🔵 What Is Ozone Gas and Why Is It Important for Mining?

Ozone is one of the strongest oxidants known. Compared to conventional chemical oxidants, it offers faster, more efficient, and more environmentally friendly performance. Since ozone decomposes back into oxygen after reaction, it provides a major advantage in industries where environmental compliance is critical, such as mining.

Key benefits of ozone:

• Extremely strong and fast oxidation

• No harmful chemical by-products

• Improves water and air quality

• Facilitates compliance with environmental regulations

• Helps reduce operational and chemical costs

🔵 Key Applications of Ozone in the Mining Industry

1. Process Water Treatment and Reuse

Water used in mining processes typically contains metals, minerals, and high organic loads. Ozone effectively oxidizes these contaminants, leading to:

• Elimination of bacteria and microorganisms

• Degradation of organic compounds

• Enhanced heavy metal precipitation

• More stable and higher-quality flotation water

This results in reduced water consumption and lower chemical usage throughout the plant.

2. Improving Flotation Efficiency

Flotation relies heavily on mineral surface conditions. Organic coatings and oxide layers on mineral surfaces may reduce reagent efficiency. Ozone treatment:

• Oxidizes organic materials on mineral surfaces

• Creates cleaner and more active mineral surfaces

• Reduces consumption of collectors and frothers

• Improves selectivity for higher-grade concentrate

OCS Ozon’s controlled dosing systems ensure that ideal ozone levels are maintained within flotation circuits.

3. Enhanced Leaching Performance

Ozone is particularly effective for refractory gold and silver ores, where traditional leaching methods may struggle.

Advantages of ozone-assisted leaching:

• Pre-oxidation of pyrite and arsenopyrite minerals

• Higher dissolution rates in cyanide leaching

• Compatibility with alternative leaching techniques such as thiosulfate

• Shorter leaching times and increased metal recovery

This results in improved extraction efficiency and reduced reagent consumption.

4. Acid Mine Drainage (AMD) Control and Environmental Management

Acid mine drainage is one of the most critical environmental issues in mining. Ozone helps reduce AMD formation by:

• Rapid oxidation of Fe²⁺ to Fe³⁺

• Controlling the excessive oxidation of sulfide minerals

• Facilitating the precipitation of heavy metal ions

• Accelerating mine wastewater treatment processes

OCS Ozon systems support environmental compliance and reduce the overall ecological footprint of mining operations.

5. Air Quality Management in Underground Mines

Air quality is essential for worker safety in underground operations. Controlled ozone application can:

• Reduce unpleasant odors

• Minimize bacterial and fungal growth

• Support ventilation systems

OCS Ozon’s automated control and monitoring systems ensure that ozone levels always remain within safe limits.
