Progress, Challenges, and Perspectives of Bioleaching for ... - Hindawi
The pH is an important physical and chemical parameter in biological leaching. In the study of bioleaching of heavy metals from tailings, iron/sulfur-oxidizing bacteria are more likely to undergo redox reactions under acidic conditions. The effect of pH on the optimum leaching rates of different metals is different.

Iron Ore - an overview | ScienceDirect Topics
Bog iron ores are found associated with peat deposits in swampy conditions. Typically they contain hydrated ferric-oxide and manganese-oxide cements but, below the water table, they may be cemented by siderite. It has been suggested that microbial activity in tropical climates particularly promotes the direct precipitation of siderite.
