Capture higher-margin chemistry from Katni's limestone: a downstream PCC unit supplying paper, paint, plastics and pharma buyers, served by the district's mining base and railway junction.

Katni runs a substantial limestone-to-cement mining belt (a recognised ODOP) feeding MP's cement industry, but raw stone earns thin margins. This is a small precipitated calcium carbonate (PCC) unit — calcination, slaking, carbonation and drying — turning high-purity local limestone into a fine, controlled-particle chemical that sells far above the raw mineral. It builds on the district's cut-stone-and-limestone-to-cement atom and the major railway junction (cheap inbound stone, cheap outbound freight to industrial buyers), and captures the raw-mineral-to-value-added-lime-products gap. PCC buyers are paper mills, paint and coatings makers, PVC and plastics compounders, and, at higher grades, pharma and food. The honest constraints are real process chemistry: limestone purity and consistent particle-size distribution are make-or-break, kiln energy management drives cost, and pharma/food grades need GMP-level quality systems and BIS conformity. The payback reflects that process and qualification ramp, not weak demand. Start with industrial-grade PCC for paint and plastics; pursue higher-purity paper and pharma grades once the process is stable.
