Technical Note on Recovery of Manganese from Low Manganese

The main constituents of ferromanganese slags are silicates of Mn Ca and AI. Factors affecting the recovery of manganese from a low manganese content ferromanganese slag (about 16 per cent MnO) during acid leaching were studied. These included time temperature agitation sulphuric acid addition solid liquid ratio and particle size.

Recovery of manganese from silicomanganese slag by means

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.

Silicomanganese production from manganese rich slag

Use of such manganese rich slag in the proportion of 40 of the blend has been found to be optimum to obtain a silicomanganese alloy with the highest metallic yield and highest manganese recovery.

Recovery of zinc and manganese from spent batteries by

the recovery of zinc and manganese present in the powder have been carried out by two acidic-reductive leachings (1) sulphuric acid/oxalic acid and (2) sulphuric acid/hydrogen peroxide. For each system the analysis of variance (ANOVA) has been performed to evaluate the behaviour of the manganese and zinc extraction yields.

slag volume and the manganese in the slag must be reduced to a greater degree to keep the recovery high. Table ill shows that the mean content of MnO in the slag is 6 28 per cent and that the manganese recovery in the second step of the two-stepBF process is 78 2 per cent. The MnO content of the slag from all three BFs was 4 93 per cent in 1990.

SlagWikipedia

Slag is the collection of compounds that are removed. In many smelting processes oxides are introduced to control the slag chemistry assisting in the removal of impurities and protecting the furnace refractory lining from excessive wear. In this case the slag is termed synthetic.

Pyrometallurgical Treatment of High Manganese

duct may easily be won from the manganiferous slag by further reduction at high temperatures ( 1600 C) whereas hydrometallurgical extraction routes only allow manganese recovery from a leach residue or as recrystal-lized Mn-salt with rather high energy consumption. Addi-tionally if Mn-recovery is not an objective the slag would FeNiCuCo Alloy
