Sulfur resource recovery based on electrolytic manganese residue calcination and manganese oxide ore desulfurization for the clean production of electrolytic manganese
An environmentally friendly and resource-conserving route to the clean production of electrolytic manganese was developed
in which the electrolytic manganese residue (EMR) was initially calcined for cement buffering; then the generated SO
2
-containing flue gas was managed using manganese oxide ore and anolyte (MOOA) desulfurization; at last
the desulfurized slurry was introduced to the electrolytic manganese production (EMP). Results showed that 4.0 wt% coke addition reduced the sulfur of calcined EMR to 0.9%
thereby satisfying the cement-buffer requirement. Pilot-scale desulfurization showed that about 7.5 vol% of high SO
2
containing flue gas can be cleaned to less than 0.1 vol% through a five-stage countercurrent MOOA desulfurization. The desulfurized slurry had 42.44 g·L

which was suitable for electrowinning after purification
and the purity of manganese product was 99.93%
satisfy the National Standard of China YB/T051-2015. This new integrated technology fulfilled 99.7% of su
lfur reutilization from the EMR and 94.1% was effectively used to the EMP. The MOOA desulfurization linked the EMP a closed cycle without any pollutant discharge
which promoted the cleaner production of EMP industry.
