    摘要： This invention generally relates to a process for manufacturing a lithium selective adsorbent and, more particularly, to a process for manufacturing a lithium selective adsorbent using a recycled and augmented intercalation reaction liquor. An initial quantity of adsorbent precursor is intercalated with lithium using an intercalation reaction liquor to produce an intercalated layered aluminate adsorbent and a post-intercalation reaction liquor. The post-intercalation reaction liquor is decanted, and the intercalated layered aluminate adsorbent is neutralized to produce the lithium selective adsorbent. The decanted intercalation reaction liquor is reconstituted to a pre-intercalation reaction volume of the intercalation reaction liquor, which is recycled to intercalate a subsequent quantity of adsorbent precursor.

    摘要： This invention generally relates to a process and circuit for reintercalating lithium aluminum double hydroxide (LADH) lithium selective adsorbents. The inventive process includes reintercalating the spent LADH adsorbent with lithium salt in a dilute brine under alkaline conditions at a predetermined intercalation temperature, followed by neutralization using an appropriate acid at a predetermined neutralization temperature. The inventive process can be performed to reintercalate the adsorbent and can be performed multiple times over the life of the adsorbent. The reintercalation process can be conducted at a chemical regeneration facility, or alternatively, in situ, such as at an on-site mineral extraction facility, in a mobile reinteractation circuit, or within adsorbent columns of a lithium extraction (e.g., DLE) circuit. In the later arrangement, the invention can be used in fixed beds, stirred tanks, pseudo- or simulated moving bed (SMB) circuits, or other DLE circuits.
