Microbially induced selective flotation of sphalerite from galena using mineral-adapted strains of Bacillus megaterium

- Cells and metabolite of B. megaterium aid selective flotation of sphalerite.
- Sphalerite-adapted cells yield highest selectivity of separation.
- A sub-set of proteins enhanced by adaptation impart higher selectivity index.
- Dissolved metal ions, protein and DNA components modulate bacterial surface charge.
