- •
The mixture of Fe2 + and S0 was optimal for bio-leaching of rock phosphates (RPs).
- •
Bio-leaching of RPs could be significantly enhanced with pre-cultivation.
- •
The mechanism involved in the enhanced bio-leaching of RPs was studied.
- •
The mechanism relies on the lower pH and the consequent decreased jarosite.
