Reagent Recycling
Closing the chemical loop for cleaner, more efficient metallurgy
Every molecule reused is one less released
PROBLEM: Reagents Drive Cost and Contamination
In metal extraction, reagents are vital — but costly and wasteful when used once.
Most hydrometallurgical processes discard them, generating chemical effluents that raise both OPEX and environmental risk.
TENSION: The ESG and Cost Equation
Effluent management and reagent procurement can represent up to 40% of total processing costs.
Tighter ESG standards now demand closed-loop systems to reduce hazardous waste and qualify for sustainable financing.
SOLUTION: Closed-Loop Reagent Recycling by Design
GEOMEGA’s closed-loop reagent recovery technology regenerates, purifies, and reuses its reagents - reducing both cost and chemical waste.
Hydrochloric acid, for example, can be regenerated directly from process streams, achieving >90% reuse while maintaining extraction efficiency.
