Lepidolite, commonly known as lithium mica, is a dominant low-to-medium grade hard rock lithium mineral widely distributed in pegmatite deposits across Southeast Asia, Africa and South America. Unlike dense and hard spodumene ore, natural lepidolite features soft texture, fine disseminated particles, high clay slime content and symbiosis with quartz, feldspar and miscellaneous mica minerals. These unique characteristics make lithium mica beneficiation far more difficult than conventional lithium ore processing, easily leading to low lithium recovery and impure concentrate if using standard spodumene flotation equipment.
A professional turnkey lepidolite plant equipped with full set lithium mica flotation complete equipment is specially engineered for refractory lithium mica ore. It adopts targeted desliming pretreatment and customized acidic flotation technology to solve the core pain points of fine particle loss and impurity overrun. This all-in-one turnkey solution covers crushing, grinding, desliming, flotation purification, concentration and dehydration, delivering stable qualified lepidolite concentrate for lithium chemical refining.
Unique Flotation Mechanism for Lepidolite Lithium Mica Ore
Lepidolite lithium mica has completely different surface chemical properties from spodumene, requiring exclusive flotation parameters and reagent systems. Most universal lithium flotation lines fail to achieve ideal separation results due to mismatched pH environment and reagent formulas.
Lepidolite flotation mainly adopts acidic cationic flotation technology. In a low-pH pulp environment, lithium mica surfaces stably adsorb cationic collectors, forming hydrophobic films to attach to air bubbles and float upward for collection. Gangue minerals such as feldspar and quartz are effectively suppressed and remain in pulp tailings. Fine slime pre-removal is the most critical pretreatment step, as excessive clay slime will consume flotation reagents and wrap lithium mica particles, severely reducing flotation efficiency and lithium recovery rate.
The complete turnkey lepidolite plant precisely controls pulp acidity, stirring intensity and bubble stability, realizing efficient separation of fine-grained lithium mica and gangue minerals, which is the core guarantee of high-quality lepidolite concentrate output.
Full Processing Flow of Turnkey Lepidolite Flotation Plant
The integrated lithium mica flotation plant adopts a mature closed-loop low-loss workflow tailored for fine-grained lepidolite ore. Every processing link and equipment matching is optimized for lithium mica’s physical and chemical characteristics, avoiding fine mineral loss and reagent waste.
Raw ore uniform feeding → two-stage closed-circuit crushing → fine closed-circuit grinding → hydrocyclone multi-stage deep desliming → pulp acidic conditioning → targeted reagent dosing → primary roughing flotation → secondary scavenging flotation → multi-stage cleaning flotation → concentrate purification → thickener concentration → full-automatic filter press dehydration → finished lepidolite concentrate stacking → tailings dry discharge
Different from spodumene processing lines, this lepidolite plant adds graded desliming and fine particle recovery modules throughout the flow, specially solving the technical difficulty of ultra-fine lithium mica loss, greatly improving the comprehensive utilization rate of low-grade lithium mica ore resources.

Core Advantages of Specialized Lepidolite Flotation Complete Equipment
Compared with ordinary universal lithium flotation equipment, the dedicated turnkey lepidolite lithium mica flotation equipment has targeted technical upgrades for fine-grained and high-slime lithium mica ore, with prominent advantages in recovery efficiency, product quality and operational cost.
Professional Desliming System Solves Fine Particle Loss
Lepidolite ore contains a large amount of fine clay slime, which is the main cause of low flotation efficiency. The complete flotation equipment is equipped with multi-stage gradient desliming devices, which thoroughly removes harmful slime before flotation. It avoids reagent adsorption waste and lithium particle wrapping, effectively recovering ultra-fine lithium mica minerals that are easily lost in traditional processing lines, increasing comprehensive recovery by 7%–12%.
Customized Acidic Flotation System for Lithium Mica
Different from alkaline spodumene flotation, this turnkey plant adopts exclusive acidic flotation formula and anti-corrosion flotation cells. The system stably controls pulp pH value and cationic collector dosage, achieving high-selectivity separation between lithium mica and gangue minerals. The finished concentrate has low impurity content and stable grade, fully meeting the requirements of lithium salt chemical processing.
Full Automatic Operation & Low Labor Cost
The complete lepidolite flotation equipment integrates PLC centralized control system, realizing automatic feeding, grinding, reagent dosing, flotation parameter adjustment and dehydration. It supports real-time data monitoring and remote fault alarm, requiring only a small number of on-site operators. The automated design greatly reduces manual operation errors and long-term labor costs for mine operation.
Energy-Saving Structure & Low Operational Consumption
All core equipment adopts energy-saving frequency conversion design. The optimized flotation cell impeller structure improves bubble utilization rate and reduces power consumption. The automatic quantitative reagent dosing system avoids manual dosing deviation and reagent waste, cutting daily chemical consumption by 20%–25%. The overall operational cost per ton of ore is significantly lower than traditional semi-automatic lepidolite processing lines.
Eco-Friendly Closed-Loop Production
The turnkey plant is equipped with complete process water circulation and tailings dry stacking systems. The water recycling rate reaches over 86%, minimizing freshwater consumption. The pollution-free tailings disposal mode complies with local environmental protection policies in major lithium mining areas, helping investors pass environmental audits smoothly and realize green and sustainable mine production.
