Manganese dioxide is a blackbrown solid occurs naturally with the formula MnO 2. Manganese dioxide (MnO 2), known as pyrolusite when found in nature, is the most plentiful of all the manganese compounds. The principal ore of manganese dioxide is pyrolusite which was known to the ancients as a pigment. Table of Contents. Manganese dioxide Structure
Ghanaian Export of Manganese Ore. Ghana is a major producer of manganese carbonate ore, an essential element needed for processing stainless steel. Mining began in 1916, controlled by the American owned African Manganese Company, and this continued until 1975, when production was taken over by the government owned National Manganese Corporation.
