Spodumene Ore Roasting Rotary Kiln Rotary Calcination For Lithium Extraction

Spodumene ore roasting rotary kiln for lithium extraction

1.Product Introduction Calcination Rotary Kiln

The Spodumene Rotary Kiln is a high-temperature calcination system specifically designed to convert natural spodumene from its -phase to a more chemically active -phase. This phase transition is critical for improving the efficiency of subsequent acid leaching processes. By utilizing precise temperature control (typically 1000–1100°C) and optimized material flow, the kiln ensures a high-efficiency phase change, serving as a core component in lithium ore extraction.

2.Application Calcination Rotary Kiln

• New Energy Battery Materials: Providing high-purity lithium salt raw materials for lithium-ion batteries.
• Metallurgy & Chemicals: Used in the preparation of lithium compounds for electrolytic aluminum, ceramics, pharmaceuticals, and other industries.
• Resource Recovery: Supporting sustainable development through the comprehensive recovery of lithium resources.

3.Working Principle Calcination Rotary Kiln

• Process Flow:

  • Raw materials enter the kiln body and achieve uniform heating through the continuous rotary motion.

  • After roasting, the resulting $beta$-spodumene undergoes acid leaching, purification, and other steps to be finalized as battery-grade lithium salts.

4.Advantages Calcination Rotary Kiln

• High Conversion Efficiency: Dramatically improves lithium leaching rates and optimizes downstream processing.

• Process Stability: An intelligent temperature control system ensures uniform heat distribution, minimizing product quality fluctuations.

• Strong Integration: Seamlessly links with crushing, flotation, and acid leaching equipment to form a complete lithium extraction production line.
