High-grade lithium mica concentrate, low-grade lithium mica raw ore, lithium mica-bearing polymetallic associated ore【Main Equipment】:
This process uses lithium mica as raw material and adopts the sulfate high-temperature roasting method to extract lithium carbonate, reconstructing the crystal lattice of lithium mica and converting it into soluble lithium salt. The entire production line integrates fully automatic workshops, realizing continuous production from raw ore to high-purity lithium salt. While ensuring lithium extraction efficiency, the process also takes into account environmental protection control and comprehensive resource utilization, and can stably meet the large-scale production requirements of battery-grade lithium salts.
Efficient and Controllable Lithium Extraction Rate
Adapted to the mineral characteristics of lithium mica, process parameters are strictly controlled to ensure a high comprehensive lithium recovery rate and low resource loss.
Compatible with ores of different grades, with a wide application scope and strong production flexibility.
Stable and Durable Kiln Equipment
Made of high-temperature resistant, wear-resistant and anti-corrosion materials, with precise gradient temperature control and uniform material heating.
Effectively avoids kiln clogging, features a long operation and maintenance cycle, and allows convenient inspection and repair.
Full-process monitoring improves the automation level.
Wide Raw Material Adaptability
Capable of processing high and low-grade lithium mica raw ore, concentrate and polymetallic associated ore, with adjustable parameters and high flexibility.
Balances comprehensive resource recovery and economic benefits.
Supports pilot testing of supplied materials and provides multiple process solutions.
Excellent Fluoride Solidification Effect
Achieves stable solidification of fluorine during roasting, preventing fluorine emission from causing equipment corrosion and environmental pollution.
Improves production safety.
Optimized Closed-loop Energy Saving and Consumption Reduction
Flue gas waste heat is recovered for raw material drying, and clinker waste heat is used for preheating mixed materials.
Significantly reduces comprehensive energy consumption and improves production economy.
