Processing Routes

Hard Rock Processing (Spodumene)

Conventional Route

1. Mining & Crushing: Ore extraction, primary crushing to -250mm
2. Beneficiation:
   • Dense Media Separation (DMS)
   • Flotation for fine recovery
   • Product: 5.5-6.0% Li₂O concentrate
   • Recovery: 65-75%
3. Calcination:
   • Heat to 1050°C (α to β spodumene conversion)
   • Energy: 1,200 kWh/t concentrate
4. Acid Roasting:
   • Mix with concentrated H₂SO₄
   • Heat to 250°C
   • Form lithium sulfate
5. Water Leaching:
   • Dissolve Li₂SO₄
   • Filter impurities
   • Solution: 20-30 g/L Li
6. Purification:
   • Ion exchange
   • Precipitation of impurities
7. Carbonation:
   • Add Na₂CO₃ at 90°C
   • Precipitate Li₂CO₃
   • Centrifuge and dry

Integrated Hydroxide Route

• Direct conversion to LiOH without carbonate intermediate
• Lower carbon footprint
• Examples: Tianqi Kwinana, Albemarle Kemerton
• Capital cost: $15,000-20,000 per tonne LiOH capacity

Brine Processing

Solar Evaporation (Atacama)

1. Pumping: Extract brine (1,500-2,000 ppm Li)
2. Evaporation Ponds:
   • 12-18 months residence time
   • Sequential crystallization: halite → sylvite → carnallite
   • Concentrate to 6% Li
3. Processing Plant:
   • Remove Mg, B, Ca
   • Precipitate Li₂CO₃
   • Purification to battery grade

Direct Lithium Extraction (DLE)

• Technologies: Ion exchange, adsorption, membrane separation
• Process Time: Hours vs months
• Recovery: 80-95% vs 40-50% evaporation
• Water Use: 90% reduction
• Commercial Status: Scaling up 2024-2027
