Pyrolusite is a mineral consisting essentially of manganese dioxide (Mn O 2) and is important as an ore of manganese. It is a black, amorphous appearing mineral, often with a granular, fibrous or columnar structure, sometimes forming reniform crusts.
The predominant types of manganese ores, according to Betekhtin (1946), are braunite-hausmannite, psilomelane-pyrolusite and psilomelane-vernadite, quartz-pyrolusite, rhodochrosite, and opal- and chlorite-rhodochrosite.
