2019-12-25 Recovery and refining of manganese as by-product from hydrometallurgical processes Lappeenranta, 2011 64 p. Acta Universitatis Lappeenrantaensis 442 Diss. Lappeenranta University of Technology ISBN 978-952-265-136-5 (PDF), ISBN, 978-952-265-135-8, ISSN 1456-4491 The consumption of manganese is increasing, but huge amounts of manganese still end up in

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. Separation of iron from manganese can be done with chemical precipitation or solvent extraction methods.

2016-6-17 Although, in lactose case, manganese recovery increased from 82.85 to 86 % by increasing acid concentration from 20 to 25 %, the 20 % acid concentration was favourable because the iron recovery was lower than that in 25 % acid concentration, where iron recovery increased from 36.75 to 47.35 % by increasing acid concentration from 20 to 25 %.

2015-12-1 A procedure for the recovery of manganese from silicomanganese slag was developed. Zn, Ni, Co and Cu are treated to remove them as pollutants. The purified liquor is suitable for electrolysis obtaining α –Mn with a purity of 99.99%. The developed process is able to recover most of the manganese (94%) in the residue.

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 MnSO4 solution with high selectivity over calcium and lead.

Synopsis The ferromanganese industry is under pressure to deal with the slag arising from the production of ferromanganese, which is discarded in landfills or slag heaps. This material poses an environmental and health risk to surrounding ecosystems and communities, and disposal costs are increasing. Ferromanganese slag contains an appreciable amount of residual manganese metal, which can be ...

2016-9-1 The recovery methods employing sulfur dioxide to dissolve the manganese offer the possibility of a manganese recovery step. This may be economic in those ores containing substantial manganese values. Parenthetically, it is felt that even very low values of manganese may be sufficient to render the silver difficult to dissolve with cyanide if ...

2015-6-15 Manganese recovery rate and losses are considered relative to typical global industry averages as determined by the LCA study for the ferromanganese supply chain. The cumulative benefits of manganese recovery at a given process stage is the sum of the benefits achieved at and upstream of the process stage as determined by Equation 1. 3.
