Manganese extraction by reduction acid leaching from low

In this work, reduction leaching of manganese from low-grade manganese oxide ores was conducted in a two-step process. At first, the low-grade manganese dioxide ore and CaS were added to a 250 mL glass flask containing 50 mL deionized water. The obtained ore slurry was then agitated at the required temperature for certain period.
