What Are Hydrogen Peroxide Emulsions in Mining?
Hydrogen peroxide emulsions (HPEs) represent a groundbreaking advancement in mining explosives technology, offering a more environmentally responsible alternative to traditional ammonium nitrate-based explosives. These innovative formulations utilize hydrogen peroxide as their primary oxidizing agent instead of nitrates, resulting in explosives that break down primarily into water and oxygen rather than nitrogen-containing compounds.
According to Thomas Gustavsson, CEO of Hypex Bio, hydrogen peroxide explosives represent a paradigm shift in blasting operations, serving as a critical advancement in mining, quarrying, and construction sectors across the SADC region (Global Mining Review, September 1, 2025).
The Chemistry Behind HPE Technology
HPEs function through a carefully engineered chemical composition that enables controlled energy release during detonation while maintaining stability during storage and handling. Unlike conventional explosives that rely on ammonium nitrate oxidizers, HPEs utilize:
- Stabilized hydrogen peroxide as the primary oxidizer
- Specialized synthetic emulsifiers resistant to peroxide degradation
- Fuel components that optimize energy output while minimizing environmental impact
- Advanced sensitizing agents that ensure reliable detonation
The manufacturing process employs cold blending techniques at ambient temperatures, significantly reducing energy consumption compared to traditional explosives production that requires heating. This cold-processing approach contributes to the overall reduced carbon footprint throughout the manufacturing value chain.
