“…This result proves that in practical electroreduction processes, only α-MnSe is formed on the cathode surface. The Se:Mn ratio further decreased, the peak (220) position of the Mn metal changed, indicating a change in the crystal formation of the metal (Galvanauskaite et al, 2011;Sun et al, 2011). The adsorption of α-MnSe affected both the electrodeposition and electrocrystallization of Mn.…”

“…SeO 2 is a key additive in industrial EM processes. Although many types of new additives have been reported (Galvanauskaite et al, 2011;Gonsalves and Pletcher, 1990a;Janickis and Stulpinas, 1958;Li and Zhang, 2011;Sun et al, 2011), SeO 2 remains to be widely used in the industry because of its high efficiency and relatively low price. It is very effective for the cathode even at trace concentrations, usually~0.3 mmol/L, compared with Mn 2+ (~0.6 mol/L) (Wei et al, 2010).…”

“…In industry EMM in most cases is produced from ammonium sulphate media using ammonium sulphate on stainless steel sheets [9][10][11]. Although many types of additives have been reported [12][13][14][15], selenium containing compounds such as selenous acid, H 2 SeO 3 , ammonium selenate, (NH 4 ) 2 SeO 4 and SeO 2 remain to be widely used because of their high efficiency. Currently studies on nonselenium additives are being investigated [16][17], with respect to environmental problems, but SeO 2 still remains to be widely used as a relatively low-cost additive in the EMM industry.…”

Water pollution in the electrolytic manganese metal (EMM) industrial production process is a serious problem, and the manganese and ammonia nitrogen concentration in the rivers near EMM plants still exceeds the standards. An environment-friendly regeneration method of the manganese electrolyte (ME) that reduces the duration of the electrodeposition process and saves water resources for ME preparation in laboratories was proposed. Thus, electrolytic manganese metal powder (EMMP) was dissolved in ME and the addition of hydroxylamine sulphate altered significantly the dissolution effect of EMMP in ME. The provided ME regeneration scheme allows to extend duration of the Mn coating deposition process up to one week without changing ME, just only adding the electrolyte prepared by dissolving EMMP in an anolyte. EMMP losses did not exceed 5–7% from the mass of the electrodeposited Mn coatings on the cathode. Ammonium selenate was dissolved in ME by periodically dissolving 2% of the salt from the mass of the electrodeposited Mn coating on the cathode at an electrolyte temperature of 30–40°C.

Tirtas elektrolitinių Mn dangų, nusodintų iš sulfatinio elektrolito, mechaninių savybių -mikrokietumo ir vidinių įtempiųkitimas esant skirtingai elektrolito temperatūrai. Nustatyta, kad kiečiausios Mn dangos nusodinamos iš rūgštaus manganavimo elektrolito su Te(VI) priedu esant 20 C ir 2 Adm -2 srovės tankiui. Panašaus kietumo Mn dangos nusodinamos ir esant 15 Adm -2 srovės tankiui bet aukštai 70 C elektrolito temperatūrai. Manoma, kad Mn dangų mikrokietumo kitimas susijęs su Te pradinėje elektrolizės stadijoje įsiterpimu į Mn dangas ir dėl to vykstančiais vidinės struktūros ir morfologijos pokyčiais. Tai turi įtakos ir tempimo vidiniams įtempiams santykinai plonose 1-2 m Mn dangose.Raktažodžiai: Mn elektrolitinis nusodinimas, Te(VI) priedas, mikrokietumas, vidiniai įtempiai.
