1999-11-17  Bog iron is a mineral iron ore also known as limonite. It forms under oxidizing conditions, because reduced iron (ferrous iron or Fe (II)) is soluble, whereas oxidized iron (ferric iron or Fe (III)) is insoluble. The oxidization can be entirely chemical-reduced iron is formed by iron-reducing bacteria which can derive energy from the process ...
