Lithium Processing Pump Project in Indonesia | UHB Slurry Pump

Descripción general del proyecto

Country: Indonesia

Sector: Lithium Battery Materials / Spodumene Lithium Extraction

The customer is engaged in spodumene lithium extraction using the sulfuric acid leaching process. The production line includes crushing and grinding, roasting, sulfuric acid leaching, impurity removal, filtration, evaporation, concentration, and lithium carbonate precipitation.

During long-term operation, the plant continuously transfers high-temperature acidic slurry and high-solid-content mineral slurry. The original metal centrifugal pumps frequently experienced casing corrosion, impeller wear, mechanical seal leakage, and excessive vibration after only 3–5 months of service.

The most severe problems occurred in the acid leaching and filter press feeding sections, where the slurry contained both sulfuric acid and fine mineral particles. The combination of chemical corrosion and abrasive wear significantly reduced pump service life and increased maintenance downtime, affecting the stability of the entire lithium production process.

Challenges in Lithium Processing Slurry Transfer

As a critical lithium processing pump application, the acid leaching process presents several operational challenges:

Strong sulfuric acid corrosion
Abrasive wear caused by fine mineral particles
High solid concentration slurry transfer
Mechanical seal leakage risks
Unstable slurry feeding performance
Continuous operation under elevated temperatures

These issues often result in frequent maintenance, reduced filtration efficiency, and increased operating costs.

Pump Solution

To address these challenges, Bomba Changyu supplied a UHB corrosion-resistant slurry pump for the acid leaching and slurry transfer sections.

The pump is specifically designed for handling corrosive and abrasive slurries commonly found in lithium processing plants, mining operations, and chemical industries.

Why UHMWPE Was Selected

The wetted components of the pump are manufactured from UHMWPE (Ultra-High Molecular Weight Polyethylene), which combines excellent corrosion resistance and abrasion resistance in a single material.

Resistencia a la corrosión

UHMWPE offers outstanding resistance to sulfuric acid and various chemical solutions used during lithium extraction processes.

Resistencia a la abrasión

The material can effectively withstand continuous erosion caused by mineral particles and high-solid-content slurry.

Reduced Leakage Risk

The external mechanical seal design helps minimize leakage and improve operational safety.

Longer Service Life

Compared with conventional metal pumps, UHMWPE-lined slurry pumps can significantly reduce wear-related failures and extend maintenance intervals.

Resultados del proyecto

After installation, the pump system achieved stable operation throughout the lithium processing plant.

The customer reported:

Reduced pump casing corrosion
Lower impeller wear rates
Improved slurry feeding stability

Preguntas frecuentes

Lithium processing plants commonly use corrosion-resistant slurry pumps to handle acidic slurries, lithium-bearing solutions, and high-solid-content mineral slurries. The pump material must withstand both chemical corrosion and abrasive wear during continuous operation.

Acid leaching slurry typically contains sulfuric acid and fine mineral particles. Traditional metal pumps are vulnerable to corrosion, impeller wear, and mechanical seal failures, resulting in frequent maintenance and reduced service life.

UHB slurry pumps combine corrosion resistance and wear resistance, making them suitable for transporting sulfuric acid slurry, lithium-bearing slurry, and filter press feed slurry. They help reduce downtime, maintenance frequency, and spare parts consumption.

Yes. UHMWPE (Ultra-High Molecular Weight Polyethylene) offers excellent resistance to sulfuric acid and many aggressive chemical solutions while also providing superior abrasion resistance against solid particles.

Depending on the operating conditions, UHB slurry pumps can handle slurries with solid concentrations of approximately 20%–30%, making them suitable for mining, lithium processing, and chemical slurry applications.

Selecting wear-resistant and corrosion-resistant materials, such as UHMWPE, and using pumps designed specifically for abrasive acidic slurries can significantly extend service life and reduce maintenance costs.
