The exploration of lithium mines around the world has remained active. This article will provide some brief introductions on the progress and trends of lithium exploration in foreign countries in 2017 and 2018. It focuses on the new progress in the exploration of pegmatitetype lithium deposits in Africa, Australia, North America, Europe, etc. The region is dominated by Africa and Western Australia, and the related progress of brine type and new type of lithium mine is the most prominent. By drawing on the new progress and new trends of foreign lithium exploration projects, it is believed that the country should enhance safety awareness, strengthen investment in exploration work, and strive to improve the selfprotection ability of key mineral resources. Find out the key domestic mineral resources, strengthen basic research work. Taking the exploration of pegmatitetype lithium ore as the leading factor, taking into account the investigation of granitetype lithium ore, and identifying the occurrence state of brinetype lithium ore and sedimentary lithium ore. Accelerate the transformation of domestic superior resources and establish a complete industrial chain. In overseas investment exploration, it is advisable to strengthen research, optimize projects, and reduce risks through various means such as cooperation.
