Pradhan Industries is setting new benchmarks in the Graphite Beneficiation Process in Odisha. With direct control over our mining zones, we utilize advanced floatation and grading technology to deliver high-purity natural crystalline graphite with a Fixed Carbon (FC) range of 80% to 95%. Our ‘Mine to Market’ approach ensures that every batch meets rigorous industrial standards for thermal conductivity and carbon recovery. In this guide, we break down the sophisticated 5-step refinement journey we use at our Odisha facilities to transform raw ore into world-class industrial carbon.
Why our Graphite Beneficiation Process in Odisha is Industry-Leading.
The 5-Step Journey of Purity: Our Beneficiation Process
Step 1: Crushing & Primary Grinding (The Liberation Stage)
The journey begins at the mine site. Raw graphite ore is trapped inside hard rock, and our first job is to set it free through a process known as Comminution.
-
Precision Crushing: We use heavy-duty jaw crushers to reduce large rocks into manageable pieces.
-
The Goal: We handle this stage with extreme precision. If you crush the ore too aggressively, you destroy the natural Large Flakes. Our priority is to liberate the graphite while keeping the crystalline flake structure intact.
Sep -2 Froth Flotation in Graphite Beneficiation Process
This is the most critical stage of the Graphite Processing in Odisha. Graphite has a unique natural property—it is hydrophobic (hates water) but loves air bubbles.
-
The Process: We place the crushed ore into large tanks called flotation cells, injecting air and specific organic reagents.
-
The Result: Pure graphite flakes cling to air bubbles and float to the surface as a “silver foam,” while the unwanted earth (gangue) sinks. This allows us to “skim” the high-purity carbon off the top.
Step 3: Regrinding & Scavenging (The Polishing Stage)
To reach our targeted 94-95% Fixed Carbon purity, we perform a second round of light grinding.
-
Why it matters: This “polishes” the flakes, rubbing away final layers of ash and silica. This ensures the carbon recovery is maximized without reducing the valuable flake size.
Step 4: De-watering & Drying (Moisture Control)
Industrial buyers require “Bone Dry” material because moisture can ruin a manufacturing batch in steel or battery production.
-
The Process: We use high-capacity vacuum filters and industrial dryers to ensure the final moisture content is below 0.5%, making it stable for global shipping.
Step 5: Classification & Screening (The Sizing Stage)
The final step is all about precision. We use high-frequency vibrating screens to sort the graphite into specific grades based on the client’s Technical Data Sheet (TDS).
| Grade Category | Mesh Size | Primary Application |
| Large Flakes | +80 Mesh | Steel & Refractory Industries |
| Fine Powders | -300 Mesh | Lubricants & Specialized Coatings |
The Pradhan Promise: Verified Purity
-
Fixed Carbon (FC): We maintain a consistent range of 80% to 95% FC, ensuring high thermal conductivity and reliability for diverse industrial applications.
-
Minimal Ash Content: Our multi-stage beneficiation process minimizes ash levels to prevent contamination during smelting and high-temperature manufacturing.
-
NABL-Certified Testing: Quality is never a guess. Every batch processed at Pradhan Industries is verified in our NABL-accredited laboratories to guarantee precision and performance.
-
Consistent Particle Size: Through advanced classification, we ensure the grain size distribution matches your exact technical requirements (TDS).
