One distinction here is between bog iron and iron in ore deposits. Bog iron is formed when ground-water picks up iron from iron-ore deposits, where that iron is then oxidized under acidic conditions to form chunks of iron minerals (goethite, magnetite, hematite, etc.), typically in smallish chunks.Web
