Zero-Emission Mineral Recovery
Leading the Way in
Closed-Loop Mineral Extraction
EcoGreen's proprietary chemical refining technology extracts strategic precious and base metals from complex electronics without hazardous pyrometallurgical smelting — returning 99.5% pure industrial raw materials to Indian manufacturers.
Critical Domestic Raw Material Purity
Our Greater Noida chemical refining line produces certified mineral outputs conforming to Bureau of Indian Standards (BIS) specifications.
| Mineral Stream | Source Material | Extraction Purity | Downstream Industrial Re-entry | Sovereign Import Offset |
|---|---|---|---|---|
| Industrial Gold (Au) | Server CPU pins, PCB bonding wires | 99.5% | Electronics plating & aerospace contacts | 100% Direct Replacement |
| Electrolytic Copper (Cu) | Motherboard traces, busbars, wiring | 99.8% | Transformer windings & EV motor wiring | Direct Domestic Feed |
| Palladium (Pd) | Multi-layer ceramic capacitors (MLCCs) | 99.2% | Automotive catalytic sensors & relays | Critical Strategic Reserve |
| Silver (Ag) | Solder joints, switch contacts, relays | 99.6% | Photovoltaic conductive pastes & optics | Solar Supply Chain Input |
| Refined Tin (Sn) | Lead-free circuit board solders | 99.4% | Industrial solder alloy manufacturing | Circular Alloy Feed |
| High-Grade Aluminium | Server chassis, heatsinks, frames | 98.5% | Structural extrusions & castings | 95% Energy Savings vs Virgin Ore |
The 4-Stage Chemical Refining Process
Ambient temperature, closed-loop chemical extraction replacing archaic smelting furnaces.
Precision Mechanical Beneficiation
Electronic boards are sheared and pulverized in sealed rotary hammer mills equipped with HEPA filtration. Electrostatic and eddy-current separators divide metallic fractions from inert epoxy substrate dust.
Selective Ambient Leaching
Concentrated metal powders undergo stage-specific acid and alkaline leaching in titanium reactors. Proprietary biodegradable chelating agents dissolve base and precious metals into pregnant leach solutions without off-gassing.
Solvent Extraction & Electrowinning
Organic solvent extraction separates copper, nickel, and precious metals into pure ionic streams. High-efficiency electrowinning cells deposit 99.8% pure copper cathodes and precipitate gold sponge.
Zero Liquid Discharge & Ingot Casting
Precipitated sponge metals are induction-melted into assay-stamped ingots. Process acids and wash waters pass through multi-effect evaporators and reverse osmosis filters, recycling 100% of liquid back into the circuit.
Strict Vetted Downstream Vendor Accountability
EcoGreen conducts semi-annual physical audits on 100% of secondary material recipients. Non-metallic fractions such as shredded flame-retardant polymers are co-processed exclusively inside authorized cement kilns as fuel substitutes, ensuring total thermal elimination with zero landfill residue.
Clients receive audited mass-balance certificates validating the exact end-state of every metric tonne consigned to our care.
