One example is manganese nodules, rocks on the seafloor composed of iron and manganese hydroxide. Manganese is used to produce industrial metal alloys, in particular stainless steel.
The last mining activity near Ilfeld ceased in 1922, but the simple statement of Peter Bancroft (1984) that "Manganite is synonymous with Ilfeld" remains true today: this is without doubt the world's best locality for crystal specimens of the black manganese hydroxide. Rarely, the district has also provided good specimens of hausmannite, pyrolusite, pseudomorphs of hausmannite after manganite, and pseudomorphs of pyrolusite after calcite--but it is almost entirely to its wonderful manganite specimens that Ilfeld owes its fame in the world of mineral collecting.
They are rich in minerals like iron, copper and manganese hydroxides.
Under oxidative conditions, on the contrary, iron and manganese hydroxides are formed and co-precipitation of radium occurs, but uranium remains in the solution [12].
