Lithium is one of the most prominent elements required to promote a variety of battery applications spanning the spectrum of cell phones, electronic tablets, renewable energy technologies, and electric vehicles. Lithium may be extracted from rock minerals such as spodumene and clays, but its recovery from brines is often considered as a more environmentally benign pathway to produce lithium carbonate. Recent direct lithium extraction technologies to produce lithium concentrate (liquid), including absorption (or ion exchange), adsorption, and nano-membrane have made notable progress toward potential commercialization in attempting to replace traditional evaporation-pond extraction. In the past decade, NETL has been developing a direct carbonation technology that can extract lithium and form lithium carbonate directly in brines at the same time, eliminating the need for absorbents, adsorbents, membranes, and a carbonation facility. Upon CO2 mixing in this work, lithium carbonate precipitated instantly under ambient conditions. Saline water appeared to promote particle growth.
