Manganese metallurgy review. Part I: Leaching of ores

Dec 01, 2007· A rather novel process for recovery of manganese with pickle liquor (weak FeSO 4-H 2 SO 4-(NH 4) 2 SO 4 solutions) from low grade manganese ores was developed by US Bureau of Mine (Brantley and Rampacek (1968)).The process is schematically shown in Fig. 1.This process features the simultaneous high temperature hydrolysis of Fe(III) and precipitation of manganese as manganese

[PDF] Hydrometallurgical Process and Kinetics of Leaching

The extraction of manganese from a semi-oxidized manganese ore was investigated with sucrose as the reducing agent in dilute sulfuric acid medium. The kinetics of leaching manganese from the complex ore containing MnCO3 and MnO2 was also investigated. The effects of sucrose and sulfuric acid concentrations, leaching temperature and reaction time on the total Mn
