The Biomining Handbook

A practical guide for biologists and mining professionals

About This Handbook

Biomining holds enormous potential for critical mineral recovery, but the field lacks a centralized resource bridging biological solutions and mining challenges. This handbook aims to address that gap.

Born from Homeworld's Biomining Under Complex Conditions Workshop, our goal is a gold-standard, technically accurate resource for both communities to design better projects together.

What you'll find:

Key biomining concepts for biotechnologists and mining professionals
Real-world examples and flowsheets of biological integration
Practical tools for evaluating biological solutions
Shared vocabulary and frameworks bridging both fields

What is Biomining?

Any biological mechanism used to aid metal recovery, mineral processing, or the management of mining-related wastes and liabilities.

Mechanisms

  • • Bioleaching & biooxidation
  • • Bioseparation & biosorption
  • • Bioprecipitation
  • • Monitoring & biosensing

Applications

  • • Heap & tank leaching
  • • Metal separation & polishing
  • • AMD treatment & closure
  • • Tailings reprocessing

Why Biomining Now?

Mining and critical mineral recovery face a new set of constraints: rising demand from clean energy, a shift toward more complex feedstocks, and tightening limits around energy, water, tailings, and social licence.

Complexity is the central issue. Most lab breakthroughs use simplified systems, but industry faces polymetallic ores, process waters with diverse co-metals, legacy wastes, and tight operational constraints.

This complexity makes conventional chemistry expensive, blunt, or risky. Biology can couple selectivity with adaptation to unlock value.
