how to mined manganese

Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with land-based mining production. Once the ore is mined, it’s transferred to a processing plant for electrolytic processing or smelting. Prior to the development of advanced technology mining equipment, freeing manganese from open pit rock beds required a lot more manpower

    Most underground mining of the manganese is generally done by room and pillar method. Mining at Nchwaning and Gloria mines uses two shafts when it was initiated in 1981, one vertical hoisting shaft that is 450m deep and another vertical shaft. Now further rooms and pillar rooms are made with low grade ore for easier mining. In this mines
