Before minerals such as spodumene and lepidolite enter the beneficiation or lithium‑extraction processes, particle‑size control directly affects mineral liberation and the efficiency of subsequent operations. When wet ultrafine grinding is applied to lithium ores, it is essential first to determine whether the objective is to enhance liberation or simply to reduce particle size—these two goals are not identical. Over‑grinding can generate substantial fines, which may be detrimental in certain flotation circuits. In designing grinding equipment, the grinding intensity should be tailored to the feed ore’s particle size distribution, mineralogy, hardness, slurry solids content, and the desired final particle size. Employing ceramic grinding media of multiple sizes enables coarse and fine particles to experience distinct grinding actions, thereby mitigating efficiency losses associated with a single‑size medium.

Cell mills are vertical, wet‑process stirred fine‑grinding machines that allow adjustment of linear velocity, charge volume, and circulation rate according to operating conditions. Prior to equipment selection in the lithium‑mining industry, it is advisable to conduct continuous pilot tests using representative, as‑received ore samples, while simultaneously measuring particle size distribution, specific electrical energy consumption, media wear, and downstream beneficiation performance indicators, thereby establishing appropriate scale‑up parameters for the equipment.
