Application of Citius Industrial Filter Cloth in the Lithium Extraction Process of Lithium-ion Battery New Energy —— Horizontal Vacuum Belt Filter Assists in Efficient Lithium Carbonate Refining
Driven by the wave of lithium-ion battery new energy, lithium carbonate, as a key raw material for power batteries and energy storage systems, is becoming the focus of global resource strategy. Extracting high-purity lithium carbonate from raw ores such as salt lakes, spodumene, and lepidolite not only tests the smelting technology of enterprises but also puts forward stringent requirements for efficient, stable, and green solid-liquid separation. In this process, Horizontal Vacuum Belt Filter has become a key equipment for continuous dehydration and efficient filtration, and its core consumable —— Industrial Filter Cloth directly affects the stability and economy of the lithium carbonate refining process.
Filtering Difficulties in Lithium Carbonate Extraction
The preparation process of lithium carbonate varies depending on the source of raw materials. Common lithium extraction processes include:
- Lithium Extraction from Salt Lake Brine : Lithium salt is extracted through pretreatment, concentration, and precipitation separation;
- Spodumene Calcination Method : Crushing, calcination, and acid leaching before entering solid-liquid separation;
- Lepidolite Sulfuric Acid Calcination Method : High-temperature calcination + Water immersion filtration;
In these processes, solid-liquid separation is a key link that connects the upstream and downstream processes. It is necessary to efficiently separate the lithium-containing solution from impurity sediment or undissolved particles to provide stable input for subsequent lithium precipitation, concentration, and crystallization. However, the lithium extraction process has the following typical separation challenges:
- Fine solid particles, easy to block;
- Some slurries have high viscosity, and the filter cake is easy to compact;
- High lithium concentration in the filtrate, uncontrollable loss;
- High environmental requirements, requiring closed and continuous processing;
Advantages of Horizontal Vacuum Belt Filter
Compared with traditional filter presses or centrifugal equipment, horizontal vacuum belt filters have the following outstanding advantages:
- Continuous operation : Can achieve 24 24-hour continuous operation;
- Controllable filtration process : The filtration area, washing area, and drying area are clearly distributed, and the process is flexible;
- Thorough washing : Multi-stage countercurrent washing effectively improves lithium recovery rate;
- Low energy consumption, simple structure : Easy to maintain and clean online ( CIP );
However, to fully utilize the performance of this equipment, it must be matched with a highly adaptable and reliable industrial filter cloth system 。
Citius Filter Cloth: A Key Aid in Lithium Extraction
Xiamen Citius Environmental Filtration Technology Co., Ltd. has been deeply involved in the field of solid-liquid separation materials 30 for years and is one of the leading enterprises in industrial filter cloth technology in China. It has long served Lithium ore extraction 、 New energy material refining and other core links. Its filter cloth products developed for lithium carbonate refining processes are widely used with mainstream horizontal vacuum belt filtration equipment at home and abroad, and have been highly recognized by customers in the lithium salt industry.
Filter Cloth Performance Advantages:
- Strong fine separation ability : Optimizing the weaving structure according to the particle distribution characteristics of lithium ore slurry ensures clear filtrate and low lithium ion loss;
- High dehydration rate : Smooth drainage channels in the fabric, and the compacted filter cake still has good filtrate discharge capacity;
- Excellent cake release : Smooth surface, anti-adhesion treatment technology reduces filter cake residue and improves equipment continuity;
- Corrosion-resistant and wear-resistant : Suitable for acid leaching systems and environments with strong mechanical tension;
- Customized processing support : Various processes such as edging, gluing, and anti-static treatment meet different usage scenarios;
The industrial filter cloth provided by Citius is suitable for key nodes such as the dehydration section after spodumene calcination and acid leaching, the lithium carbonate precipitation and washing section in salt lake lithium extraction, and the solid-liquid separation section in lepidolite calcination and lithium extraction, effectively reducing the frequency of filter cloth replacement and improving production line efficiency.
Application Results and Customer Feedback
In the pilot test of a large lithium salt enterprise's production line, Citius customized a filter cloth solution for its horizontal vacuum belt filter, compared with the original imported filter cloth solution:
- Shorter filtration cycle 15%；
- Reduced lithium loss in filtrate 0.3% ；
- Filter cloth lifespan increased by approximately 30%；
- Washing water reduced by approximately 20%；
This not only brings about a direct reduction in operating costs, but also improves the purity and recovery rate of lithium carbonate products.
Conclusion: Lithium extraction technology is moving into deeper waters, and the value of filter cloth continues to increase.
As lithium resource development shifts from rich ores to medium and low-grade ores and complex salt lakes, lithium extraction processes are becoming increasingly refined and green. Industrial filter cloths, though small, are irreplaceable throughout the entire lithium extraction chain. “ Micro-technology nodes ” Xiamen Dias will continue to leverage its professional R&D capabilities and rich industry experience to help lithium-ion battery and new energy companies continue to advance on the path of green and high efficiency.
