Evaporation Crystallization for Lithium Battery Recycling
Integrated Evaporation & Crystallization Systems for Battery Recycling Hydrometallurgy
As lithium-ion battery recycling expands, recyclers face increasing pressure to recover more valuable materials, maintain consistent product quality and reduce the cost of treating complex process liquors.
Hydrometallurgical recycling of lithium-ion batteries can generate lithium-bearing solutions, concentrated salt streams and wastewater containing varying levels of sodium, potassium, sulfates, chlorides and residual impurities. Their composition depends on the battery chemistry and upstream recovery process.
Turning these streams into recoverable products requires more than simply removing water. Evaporation, crystallization, impurity control, solid-liquid separation and mother liquor management must work together to achieve reliable performance.
Myande provides evaporation and crystallization solutions for lithium battery recycling, integrating process engineering, energy-efficient concentration, controlled crystallization, separation and automation.
Our systems are designed around your actual solution composition, target products, recovery objectives and utility conditions.

Integrated Evaporation & Crystallization Process
The actual process configuration depends on the upstream hydrometallurgical route and the required recovered products.
1. Feed Analysis & Conditioning
Incoming process liquor is evaluated for lithium content, dissolved salts, impurities, pH and other properties that influence concentration and crystallization.
2. Evaporation & Concentration
Water is removed through an evaporation system selected according to solution chemistry, required concentration and energy conditions.
3. Controlled Crystallization
Temperature, concentration, supersaturation and residence time are managed to promote the crystallization of the intended salt product.
4. Solid-Liquid Separation
Crystals are separated from mother liquor using equipment matched to the crystal properties and required recovery efficiency.
5. Product Washing & Drying
Where required, washing and drying help achieve the specified product purity, moisture and handling characteristics.
6. Mother Liquor & Condensate Management
Residual streams are evaluated for recycling, additional resource recovery, water reuse or appropriate downstream treatment.
Lithium Recovery and By-product Salt Management
Lithium recovery is influenced by the entire hydrometallurgical process, including upstream purification and downstream crystallization.
Depending on the recycling route, Myande's evaporation and crystallization systems can support the concentration or recovery of lithium-bearing solutions and selected salt streams.
Potential applications include:
Lithium-Bearing Liquor Concentration
Prepare suitable lithium-rich solutions for downstream chemical conversion, purification or crystallization.
Lithium Salt Processing
Support selected lithium salt crystallization and refining operations according to the agreed product route.
Sodium & Other Salt Recovery
Evaluate crystallization of suitable by-product salts where their composition and market requirements justify recovery.
Residual Mother Liquor Treatment
Reduce liquid waste volumes and assess additional recovery or treatment options.
Not every salt stream can be economically separated into a marketable product. Myande evaluates the recovery route against feed chemistry, required purity, operating cost and downstream demand.

FAQ
-
Can Myande provide a complete lithium-ion battery recycling plant?
-
Myande's solution is focused on evaporation, crystallization, concentration, separation and related process integration. Complete battery recycling may also require discharging, dismantling, shredding, leaching, solvent extraction and other technologies, depending on the selected route. The final scope is defined for each project.
-
-
Can the system handle both LFP and NMC recycling solutions?
-
Potentially, yes. However, the solution chemistry and upstream process route must be evaluated. Equipment configuration, materials selection, crystallization conditions and recovery strategy may differ significantly.
-
-
Can evaporation and crystallization recover battery-grade lithium carbonate?
-
These systems can support lithium concentration and selected refining stages, but achieving battery-grade lithium carbonate depends on the full purification and chemical conversion route. Evaporation and crystallization alone do not guarantee battery-grade product quality.
-
-
Which evaporation technology is most energy-efficient?
-
MVR, multi-effect evaporation and TVR have different advantages. The appropriate choice depends on feed composition, boiling point elevation, fouling behavior, steam and electricity costs, capacity and operating requirements.
-
-
How can lithium losses in mother liquor be reduced?
-
Potential measures include optimizing crystallization, improving separation and washing, and evaluating mother liquor recycling or additional recovery stages. Impurity accumulation must be considered before increasing recycle rates.
-
-
Can the system achieve zero liquid discharge?
-
A zero liquid discharge configuration may be technically feasible for suitable streams, but it requires a complete assessment of water recovery, residual salts, impurity management and final waste handling. It should not be assumed for every recycling process.
-
-
Can Myande upgrade an existing evaporation system?
-
Yes. Myande can evaluate the existing process and identify opportunities for energy optimization, debottlenecking, crystallization improvements, automation and water recovery.
-
-
