Introduction to LCT (Li-Cs-Ta) Type Pegmatite Exploration Technology to Secure Raw Minerals (Li) for Batteries

Abstract

The occurrence mode of lithium, a critical element in the battery industry, can be categorized into three types. Among these, the hard rock-type, particularly the LCT (Lithium-Cesium-Tantalum) pegmatites, stands out for its exceptional cost-effectiveness and developmental efficiency. LCT pegmatites originated from S-type granites; they exhibit compositional characteristics consistent with fertile granite and are enriched in Li, Cs, Be, Sn, Ta>Nb, B, P, and F. Leveraging these geochemical attributes, LCT pegmatites can be effectively explored by considering distinct factors such as the distribution of source rocks, geotectonic environment, and age dating. Current research deals with LCT pegmatites located in Uljin, South Korea, employing appropriate exploration methods including geophysical exploration and structural and geochemical analysis. The future objective involves constructing a 3D subsurface orebody model through the spatial integration of data derived from various exploration methods.
