ABSTRACT:
A low grade ferruginous Mn ore assaying 21.77%Mn and 28.53%Fe mines of Sandur region was subjected to amenability to beneficiation process comprising of -wet screening over 10,6,3,1mm-split jigging of screen over sizes in a mineral jig,-crushing of jig tails to -1mm–magnetizing reduction roasting of crushed jig tails and natural minus 1 mm powder 600oC for 0.5 hour with 10% coal reductant followed by water quenching and wet low intensity magnetic separation to remove ferruginous impurities yielded a composite concentrate assaying 32.36% Mn, 21.53% Fe,1.5 Mn/Fe ratio with 68.7% Mn distribution at 46.2 wt.% yield meets the specifications of metallurgical industry after suitably agglomerating the concentrate. The sample is amenable to processing
