LANXESS launches ion exchange resin for lithium extraction

German specialty chemicals company LANXESS has added Lewatit TP 308 to its range of selective ion exchange resins, which are ideally suited for the purification of lithium salt solutions. “Purification processes of this type play an important role to create the ultrapure lithium salts needed in the production of lithium batteries and rechargeable lithium-ion batteries,” said Dirk Steinhilber, Technical Marketing Manager at the Liquid Purification Technologies business unit at LANXESS. 

The use of ion exchange resins offers a number of advantages over the traditional method of final polishing for lithium brine, which is based primarily on precipitation operations. As Steinhilber explained, “Using ion exchange processes for calcium removal cuts both the time and expenditure needed by a significant margin.” 

The macroporous Lewatit TP 308 has been developed specifically to treat low-concentration lithium salt solutions (cLi < 2 g/l) containing alkali, alkaline earth and heavy metals at relatively high concentrations ranging from 100 mg up to several grams per liter. Such solutions occur, for example, during the treatment of geothermal brine following the desorption from primary adsorber material. 

The removal of the polyvalent ions – mainly calcium – from these solutions takes place very efficiently, with low leakage, and at high flow rates owing to the exceptional exchange kinetics. At the same time, the pressure drop across the resin bed is low. Laboratory testing has demonstrated the superior performance of Lewatit TP 308 compared with various products from competitors. 

One particularly impressive feature of the resin is its high total capacity of more than 4.3 eq/l (equivalents per liter). This means better service lives and thus longer intervals between the regeneration phases than is the case with standard resins. Consequently, the specific need for regeneration chemicals and scarce water is reduced. This results in an overall improvement in system availability coupled with lower operating costs. “A specially modified polymer structure for the resin ensures a long lifespan even in the case of frequent regeneration and makes the process a much more attractive prospect in financial terms,” said Steinhilber.
