Candle Sintered Filter Element for Lithium Extraction from Ore

Product Details

The candle sintered filter element for lithium extraction from ore is a core filtration component specially designed for solid-liquid separation in processes such as acid leaching, extraction and precipitation of lithium ore. It is made of 316L stainless steel / titanium alloy powder through high-temperature sintering, featuring a candle-shaped cylindrical structure, compatible with candle filters, and efficiently intercepting fine solid particles and impurities in lithium ore slurry.

With a gradient porous three-dimensional structure, the filter element has controllable pore size (1–50μm), high porosity, large dirt-holding capacity for depth filtration, and filtration efficiency ≥99.9%, ensuring the purity of lithium liquid and product quality. The material is resistant to strong acids, alkalis, high temperatures (long-term 200℃) and pressure (1.6MPa), suitable for harsh working conditions such as lithium ore leaching solution and concentrated solution.

Adopting an asymmetric gradient design, it has large flux, low pressure drop, easy regeneration via backflushing / chemical cleaning, reusable for more than 50 times, service life of 3–5 years, reducing operating costs. Flexible specifications: outer diameter 30–85mm, length 500–2000mm, customizable interfaces, compatible with various candle filtration equipment.

Totally enclosed filtration without leakage, modular design for easy installation and maintenance. It is widely used in lithium ore acid leaching residue separation, lithium salt crystallization and refining processes, serving as an efficient, stable and economical core consumable for solid-liquid separation in lithium extraction from ore.
