Dry deep screening of spodumene and its mineral processing
The spodumene ore used in the screening tests came from a spodumene mine. The curves of the particle-size composition and cumulative particle-size characteristics of spodumene are shown in Fig. 1.The material was mainly composed of four particle-size classes, 0–0.8 mm, 0.8–1 mm, 1–3 mm, and 3–6 mm, and the proportion of each particle-size class decreased in turn.
