Beneficiation Of High Silica Manganese

Rapid depletion of high grade Manganese ore reserves and increased industrial demand necessitated the Indian mineral industries to look for low grades ores and fines rejects. As per the present practices in Central India, Mn-ores from old working and

Few of the main misconcepts are- 1)Sinters bring no benefit – technical or economical.2) Sinters are very friable and disintegrate easily into high fines during handling/transportation. 3) Fines below 100 mesh cannot be sintered. 4) Silica increases to high level during sintering, resulting in to high slag volume thereby higher power consumption

4) Silica increases to high level during sintering, resulting in to high slag volume thereby higher power consumption. All are false. Sinters have already been proved to bring enormous technical benefits in smelting operation.

May 10, 2016 The ore contains around 23% Mn and 28% Fe with around 7% of combined alumina and silica. Such Mn ore has not found any use because of its sub-grade nature and high iron content, and is hence considered as waste. The ore does not respond to any physical beneficiation techniques because of the combined state of the manganese and iron phases
