This lepidolite roasting system primarily uses lepidolite as raw material, adopting a sulfate high-temperature roasting method to extract lithium. The lepidolite crystal lattice is restructured to convert lithium into soluble salts. The entire production line integrates fully automated sections, enabling continuous production from raw ore to high-purity lithium salts. While ensuring lithium extraction efficiency, the process also emphasizes environmental control and comprehensive resource utilization, reliably meeting the requirements for large-scale production of battery-grade lithium salts.

1. Efficient and controllable lithium recovery

Tailored to lepidolite mineral characteristics with strict parameter control, ensuring high overall lithium recovery and low resource loss. Compatible with various ore grades, offering high production flexibility.

2. Stable and durable kiln equipment
Constructed with high-temperature resistant, wear-resistant, and corrosion-proof materials. Precise gradient temperature control ensures uniform material heating. Effectively prevents ring formation and clogging, extends maintenance cycles, and simplifies repairs. Full-process monitoring enhances automation.

3. Wide raw material adaptability

Capable of processing high/low-grade lepidolite ores, concentrates, and polymetallic ores with adjustable parameters. Balances resource recovery and economic benefits. Pilot tests available with multiple process solutions.

4. Excellent fluoride immobilization

Achieves stable fluorine fixation during roasting, preventing fluorine escape that causes equipment corrosion and environmental pollution. Enhances operational safety.

5. Closed-loop energy saving and consumption reduction

Flue gas waste heat recovered for raw material drying; hot material waste heat used to preheat feed mixtures. Significantly reduces overall energy consumption and improves economic efficiency.
