Ferric iron plays a key role as a leaching agent. In ferric leaching, the generated ferrous iron can be biologically regenerated by biooxidation. In commercial applications, microbial growth usually limits operational conditions such as iron concentration and pH. Therefore, design and operation are often conditioned by strict restrictions of...

The utility of ferrous iron biooxidation is to regenerate Fe(III) at required rates and conditions in specific hydrometallurgical contexts, such as metal extraction from ores/concentrates and mining and electronic waste. In these applications, considerable kinetics improvements can be achieved by increasing [Fe(III)], but pH must be decreased...
