Limestone Threshold Value
•As per beneficiation study carried out by NCCBM and IMMT it is known that only 2 to 3% CaO enrichment can be done through dry beneficiation. •The present cut off grade for limestone is 42% so that after blending with high and low grade, we achieve ultimate requirement of around 44.5% CaO.
