Low-cost recovery of copper and cobalt from mining waste in Zambia

environmentPilotedTRL 7

Imagine a giant pile of old mining waste that's too expensive to clean up but still contains valuable metals. Instead of using expensive machinery, this project uses special bacteria in a pond to eat away the rock and release the metals. It's like using a natural biological filter to turn trash into treasure without spending a fortune on factories.

The business problem

What needed solving

Mining companies have billions of tonnes of low-grade waste that are too expensive to process using current tank methods, creating both a lost profit opportunity and a long-term environmental risk.

The solution

What was built

A low-cost pond bioleaching system and environmentally friendly SX reagents for extracting copper and cobalt.

Who can put this to work

Mining
enterprise
Target: Mining operator with legacy tailings

If you are a mining operator dealing with billions of tonnes of waste—this project developed a pond bioleaching system that recovers cobalt and copper at a lower cost than traditional tanks. This turns an environmental liability into a revenue stream.

Chemicals
SME
Target: Specialty chemical manufacturer

If you are a chemical manufacturer dealing with toxic extraction agents—this project developed new environmentally friendly SX reagents for metal separation. This allows for cleaner production of refined cobalt and copper for the EU market.

Environmental Remediation
mid-size
Target: Mine closure specialist

If you are a remediation firm dealing with sulfidic tailings risks—this project developed a bioleaching process that produces benign residues. This reduces long-term environmental liabilities for mine sites.

Frequently asked

Quick answers

How does this affect operational costs compared to current methods?

The pond bioleaching system sharply reduces capital and operating costs compared to conventional tank bioleaching, making recovery viable for lower-grade materials.

At what scale is the technology being tested?

The system will be demonstrated at TRL7 using Mopani mine tailings in Zambia.

What is the IP or licensing status for the reagents?

Based on available project data, the project is developing new environmentally friendly SX reagents, but specific licensing terms are not yet disclosed.

What is the timeline for the project results?

The project runs from 2026-06-01 to 2029-11-30.

How does this integrate into existing EU supply chains?

The process yields refined cobalt and copper specifically intended for EU markets to secure and diversify critical raw material access.

Consortium

Who built it

The consortium is well-balanced for commercialization, featuring 14 partners across 8 countries. With an industry ratio of 43% (6 industrial partners), the project has strong market pull, while the inclusion of 3 SMEs suggests a focus on agile technology deployment and specialized reagent development.
