A Lithium Extraction Project from a Salt Lake


In this project, VONTRON's membrane products demonstrated excellent rates of Mg and Ca rejectionThe membrane specifically designed for salt lake lithium extraction and boron removal achieved a boron removal rate of over 70% in the primary boron removal process, significantly outperforming a certain competitor's product.

 

Process Technology: old brine + resin adsorption unit + pretreatment + multi-stage NF nanofiltration separation unit + multi-stage RO concentration unit + ion exchange for magnesium removal + multi-stage NF nanofiltration for boron removal + MVR evaporation concentration + chemical precipitation of lithium + drying treatment + industrial-grade lithium carbonate.
