Lepidolite lithium mica ore remains a cost-effective and sustainable lithium resource for global new energy manufacturing, widely mined in Southeast Asia, Africa and South America. Unlike hard and high-grade spodumene, natural lepidolite features fine disseminated grains, high clay slime content and complex symbiosis with quartz, feldspar and other gangue minerals, requiring matched crushing, milling and flotation systems to achieve qualified concentrate. A 30–500TPD full lepidolite plant integrating complete crushing, milling and flotation units is a modular, scalable turnkey solution tailored for small and medium-sized lithium mica mines.
This full-process lepidolite production line covers flexible capacity from 30TPD micro pilot scale to 500TPD formal commercial production, realizing one-stop ore processing from raw ore size reduction to final lithium concentrate output. Different from scattered single equipment configuration, the integrated crushing milling flotation line perfectly matches particle size grading, grinding fineness and flotation parameters, effectively solving common lepidolite beneficiation problems such as uneven grinding, serious fine particle loss and low lithium recovery.
Complete Process Logic of Lepidolite Crushing Milling Flotation Line
Lepidolite beneficiation success depends on coordinated three core links: precise crushing control, graded fine milling and targeted acidic flotation. Every process step of the 30–500TPD full lepidolite plant is optimized for lithium mica’s physical and chemical characteristics, avoiding over-crushing, over-grinding or insufficient mineral dissociation that restricts flotation efficiency.
Crushing and milling serve as the pre-beneficiation foundation to liberate monomer lithium mica particles from gangue minerals, while flotation acts as the core separation unit to remove impurities and upgrade concentrate. The whole production line adopts closed-circuit circulation design to reduce ore waste and reagent consumption, ensuring stable and efficient operation of small and medium-scale lepidolite mining projects.
Standard Full Flow of 30–500TPD Lepidolite Processing Line
The integrated crushing, milling and flotation line adopts a mature low-loss closed-loop workflow, realizing continuous and automatic production of lepidolite concentrate. The compact and reasonable process layout adapts to limited site conditions of remote small-scale mines.
Raw ore uniform feeding → primary jaw crushing → secondary fine crushing → vibrating screening classification → closed-circuit ball mill milling → hydrocyclone grading & deep desliming → pulp acidic conditioning → automatic reagent dosing → roughing flotation → scavenging flotation → multi-stage cleaning flotation → concentrate thickening → filter press dehydration → finished lepidolite concentrate stacking → tailings dry discharge
Compared with ordinary lithium processing lines, this full lepidolite plant adds multi-stage desliming and fine particle recovery modules after milling. It thoroughly removes clay slime generated during crushing and grinding, prevents reagent failure caused by slime adsorption, and greatly improves the utilization rate of fine-grained lithium mica ore.

Technical Advantages of Integrated Crushing Milling Flotation Design
The 30–500TPD full lepidolite plant integrates optimized crushing, milling and flotation technologies, solving the mismatch problem of separate equipment configuration in traditional lepidolite processing lines, with prominent advantages in beneficiation stability, cost control and resource utilization.
Graded Crushing & Milling Improve Ore Liberation
The two-stage closed-circuit crushing system controls raw ore particle size uniformly, avoiding excessive coarse particles and excessive fine powder. The matched closed-circuit ball mill and hydrocyclone grading system precisely controls grinding fineness, fully dissociating monomer lithium mica from gangue minerals. Uniform pulp particle size creates stable flotation conditions, laying a foundation for high-efficiency lithium separation.
Targeted Desliming & Acidic Flotation for Lepidolite
Aiming at the high slime characteristic of lepidolite ore, the full plant removes harmful fine clay slime after milling, eliminating reagent waste and lithium particle wrapping. The exclusive acidic flotation system adopts cationic collector formula suitable for lithium mica, achieving high-selectivity separation between lepidolite and quartz-feldspar gangue. The finished concentrate features stable grade and low impurity content, meeting lithium chemical refining standards.
Flexible Scalable Capacity for Phased Production
The modular integrated design supports free capacity adjustment between 30TPD and 500TPD. Mine owners can start with micro-capacity trial production to reduce initial investment risk, and gradually expand crushing, milling and flotation units according to ore reserve growth and market demand. The reserved expansion interface avoids overall equipment reconstruction, realizing phased low-risk project investment.
Low Energy Consumption & Cost-Effective Operation
All crushing and milling equipment adopts energy-saving frequency conversion design, reducing invalid power consumption during ore processing. The automatic quantitative flotation dosing system avoids manual dosing errors and chemical waste. The integrated compact layout reduces site construction investment and daily labor input, with comprehensive operational cost significantly lower than traditional split-type lepidolite processing lines.
Eco-Friendly Closed-Loop Green Production
The full lepidolite plant is equipped with complete process water circulation and tailings dry stacking systems. The water recycling rate reaches over 85%, effectively saving freshwater resources. Zero-discharge tailings disposal mode complies with local environmental protection policies in Africa, Southeast Asia and other major lithium mining areas, helping projects pass environmental audits smoothly.
