Provided is a method of economically recovering manganese from low-grade minerals and manganese-containing waste. Iron-reducing bacteria and a manganese-containing substance to be treated are mixed in a treatment solution containing trivalent iron ions, the trivalent iron ions are reduced to divalent iron ions by means of the iron-reducing bacteria, manganese ions are leached from the treated

Recovery of Manganese Ore Tailings by High-Gradient

16/08/2017 With the depletion of high-grade manganese ores, Mn ore tailings are considered valuable secondary resources. In this study, a process combining high-gradient magnetic separation (HGMS) with hydrometallurgical methods is proposed to recycle fine-grained Mn tailings. The Mn tailings were treated by HGMS at 12,500 G to obtain a Mn concentrate of 30% Mn with the recovery efficiency of 64%.

Leaching Method for Recovering Silver & Manganese

25/02/2018 Manganese recovery ranged from 60 to 95 pct for oxide and carbonate deposits. As an offshoot of this project, the feasibility of recovering silver and manganese from refractory silver deposits was evaluated. These deposits are refractory because the silver Is either bound with the higher order manganese oxides, rendered inaccessible to cyanide leach solutions by the surrounding manganese
