Beneficiation of low grade manganese ore fines D. S. Basu D. Pal K. P. Ghost,• ABSTRACT The availability of ferro-manganese grade ore is limited in India while the requirement of this grade of ore is expected to increase manifold, considering the projected steel production of about 30 million tons by 2000 A. D.
Low-grade manganese ore is beneficiated with hydrochloric acid as a leaching agent to obtain a manganese concentrate. Hydrochloric acid can then be regenerated using cheaper sulfuric acid via contact with the leach liquor (a CaCl 2 solution), whereas calcium sulfate whiskers can also be precipitated during this regeneration.
And the growing need for manganese ores makes the beneficiation of low-grade manganese ores more economical. In this study, the characterization and beneficiation studies were carried out to.
Low-grade manganese ores contain cryptomelane, romanechite, amorphous manganese hydroxides, birnessite, pyrolusite, hematite, quartz, kaolinite, illite (hydromuscovite), montmorillonite and.
At present, commonly used manganese ore beneficiation methods include physical beneficiation (washing and screening, gravity separation, strong magnetic separation, flotation separation, joint beneficiation), chemical beneficiation (leaching method) and fire enrichment, etc. 1.
During mining, beneficiation and transportation of these manganese-bearing ores up to 30% of the ore produced is converted into −10 mm low grade Mn ore fines. Indian manganese ore deposits occur as bedded sedimentary deposits and found in Madhya Pradesh, Maharashtra, Gujarat, Andra Pradesh and Orissa states.
