Indian Iron-Ore Beneficiation + Pellet Plant MEP — worldsteel + USEPA RRR + CPCB + GISTM
A 5 MTPA Indian iron-ore beneficiation + pellet plant demands ₹2,645 Cr MEP capex with crushing + screening + jigging + spiral + ball mill + pellet plant + induration furnace + SCR + bag-house + ETP + TSF. worldsteel + USEPA NESHAP RRR + CPCB + GISTM + IBM + DGMS govern. Three failures: induration NOx/SOx/PM control inadequate (legacy 80-120 vs CPCB 30 mg/Nm³ limit), tailings dam GISTM non-compliance (65 % Indian TSF flagged), water recycle < 85 % violating CGWB allocation.
Indian iron-ore beneficiation + pelletisation framework
Indian iron-ore (Bailadila Chhattisgarh + Bellary + Sandur Karnataka + Singhbhum Jharkhand + Goa) miners (NMDC + SAIL + Tata Steel mines + JSW + Vedanta + Adani) operate beneficiation + pellet plants. Standards stack — DGMS + IBM + worldsteel + USEPA NESHAP Subpart RRR + Indian Bureau of Mines Mineral Conservation + Development Rules 2017 + IS 1448 (iron-ore sampling) + ISO 4701 (iron ore size analysis) + CPCB Iron Ore Emission Norms 2022.
Iron-ore beneficiation + 5 MTPA pellet plant MEP scope
| Process unit | Equipment | Capacity | Capex (₹ Cr) |
|---|---|---|---|
| ROM crushing + screening | — | 3500 t/hr | 285 |
| Wet washing + jigging | — | — | 125 |
| HMS heavy-media separation | — | — | 85 |
| Spiral concentrator + WHIMS | — | — | 125 |
| Ball mill / rod mill | — | 25 MW | 220 |
| Pellet plant — disc/drum balling | green pellet | 5 MTPA | 485 |
| Induration furnace (gas-fired) | indurated pellet | — | 620 |
| Pellet cooling | — | — | 85 |
| Tailings dam (TSF) | 5-yr storage | GISTM | 185 |
| Process water + recycle | 85 % | — | 35 |

| Bag-house + ESP (induration flue) | PM < 30 + SO2 + NOx | CPCB | 125 |
| Conveyor + dispatch | — | — | 85 |
| Total beneficiation + pellet plant | — | — | 2,645 |
Three Indian iron-ore beneficiation MEP failures
- Induration furnace SCR/dust capture inadequate — induration at 1300°C produces NOx + SOx + PM. CPCB 2022 + USEPA require SCR + bag-house + dry scrubber to PM < 30 mg/Nm³. Indian legacy pellet plants emit 80-120 mg/Nm³.
- Tailings dam without GISTM compliance — Brumadinho-class breach risk on Indian pellet TSF. GISTM compliance demands instrumentation + EAP + independent review. Indian Bureau of Mines + DGMS audit found 65 % Indian TSF non-compliant 2024.
- Water recycle < 85 % — beneficiation uses 1-2 m³/t-ore. Without 85 %+ recycle, freshwater abstraction violates CGWB + state-level water allocation. Specify thickener + filter press + closed-loop per GISTM.
