Manganese occurs in nodules on the bottom of the ocean and in most iron ores. The manganese content in coal has been reported to be 6–100 μg/g (Ruch et al., 1973). Manganese also occurs over a wide range of concentrations as a natural trace element in crude oil. Most manganese is mined in open pit or shallow underground mines.
