In the present research, manganese ore samples were collected from Popa Mount in Mandalay Region and Pawe Island in Tanintharyi Region. Pyrolusite is a mineral consisting essentially of manganese dioxide and is important as manganese ore. According to EDXRF data, the presence of Mn, Ca and Sr in Popa manganese ore sample and Mn, Fe, Ba, K, Ca, Cu, Zn, Sr, Ni and Zr in Pawe manganese ore
Oct 12, 2018 Manganese Mn extraction from iron-rich pyrolusite ore with cheap sulphur dioxide is considered to be the most promising method with advantages of rapid leaching rate and high leaching efficiency. Nevertheless, co-dissolution of iron Fe with manganese has limited the development of its commercial practice.
