Research collaboration for an “eco-friendly” direct carbonation lithium beneficiation process

The German Federal Ministry of Education and Research (BMBF) has awarded a grant to ANZAPLAN and the Freiberg University of Mining and Technology to develop, optimize and scale a process for direct carbonation of lithium bearing raw and recyclable materials.

The direct carbonation process is a highly selective low chemical consumption process using supercritical CO2.

The goal for the lithium bearing primary and secondary raw materials is to recover lithium using CO2 with reproducible lithium yields of more than 95%. The recycling target of lithium ion batteries is to recover lithium from the “black mass” to a marketable Li2CO3 with battery grade quality (BG-Li2CO3,> 99.5%). Both raw material and recycling routes are to be developed using the low chemical consumption process. ANZAPLAN is proud to be developing and evaluating this exciting project.
