Recovery and refining of manganese as by-product from

The consumption of manganese is increasing, but huge amounts of manganese still end up in waste in hydrometallurgical processes. The recovery of manganese from multi-metal solutions at low concentrations may not be economical. In addition, poor iron control typically prevents the production of high purity manganese.

Selective Recovery of Manganese from Anode Sludge

This work demonstrates a novel method for selective manganese recovery from lead- and calcium-bearing manganese oxide solid residue. Leaching with sulfuric acid in the presence of a selected reducing agent, such as hydrogen peroxide or citric acid, yields a concentrated MnSO 4 solution with high selectivity over calcium and lead.

Manganese Mining and Processing: Everything you Need

The Manganese Mining Process. More than 25 million tons of manganese are mined every year. 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
