Lithium is one of the key components for future electric vehicle batteries and energy storage. The future availability of lithium to meet demands remains in question. Around 60% of lithium resources exist in the form of continental brines. Traditional methods use precipitation and have found limitations in lithium extraction due to interference of Mg in high Mg/Li brines. Thus, highly selective adsorbents in the form of spinel structured delithiated lithium manganese oxide have demonstrated promising results. However, due to the small particle sizes, it is economically difficult to recover the adsorbents and thereby limiting industrial applications. In our work, LiMn2O4 ion sieve was synthesized and immobilized simultaneously on diatomaceous earth. Fundamental adsorption studies were carried out in lithium buffer solutions to understand the nature of adsorption and kinetics. The adsorbents were also tested for recycling stability as well as with Great Salt Lake brine samples.
