This paper compares the efficiency of D2EHPA and Cyanex 272 to extract the divalent manganese cation from an actual leaching solution obtained by reductive leaching of a low-grade pyrolusite ore using SO2 gas.

Leaching of pyrolusite using molasses alcohol wastewater as a ...

Therefore reductive atmospheric leaching of pyrolusite ore using molasses alcohol wastewater and sulphuric acid medium is a feasible technology for extracting manganese. Considering that the process productively uses molasses alcohol wastewater from the sugar industry the technology should be beneficial from both an economic and an environmental perspective.

Pyrolusite - Wikipedia

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. It has a metallic luster a black or bluish-black streak and readily soils the fingers.
