Manganese is mostly extracted at open-cast mines, using explosives and excavators. There are also several underground Manganese mines (mostly in South Africa like the Wessels, Gloria and Nchwaning mines, but also in India, Mexico, etc.). Underground operations use block-caving, room-and-pillar, modified cut-and-fill or longwall mining
