Definitions, mechanisms, and where biotech rivals chemistry
Our Definition
"Biomining" is often shorthand for "microbes in heaps." That definition is too narrow. For this handbook, biomining means:
Any biological mechanisms—cells, enzymes, proteins, plants, metabolites, or consortia—used to aid metal recovery, mineral processing, or the management of mining-related wastes and liabilities. This includes cell-free proteins and separation modules as well as whole-cell systems.
The Bottom Line
Biomining is not a replacement for mines. It's a toolkit of modules that can plug into existing flowsheets where:
•Complexity makes conventional chemistry expensive, blunt, or risky
•Selectivity, adaptation, or operation under milder conditions offer strategic advantages
•Environmental outcomes (closure, water quality, social licence) add value beyond metal recovery
These modules are judged on the same metrics as any other process: $/tonne, % recovery, impurity removal, risk, permitting footprint, and closure outcomes.
