Core Recycling Techniques

Recovery of Explosive Residues

After blasting, rester explosive materials - including undetonated prills, emulsion matrices, and ANFO (amonium nitrate fuel oil) fines - are collected from blast sites, stocpile areas, and boreholes.

Advanced Reuse Strategies

Modular Blasting Systems

Therese systems allow for quick reconfiguration and reuse of explosive across anross mining sites. Instead of disposing of partially used bulk emulsion or ANFO after a single blast, modular tanks and pump trucks can return unused material to a central reprocesing plant.
