Abstract: Tin is a very important strategic metal mineral.The distribution of global tin resource is uneven. The tin resource mainly concentrated in China, Russia, Indonesia, Egypt, Brazil and Australia. Most deposit scale are mainly small and medium.The global tin proven reserve and exploration degree is low. With growing demand of the semiconductors, new energy vehicles and construction of 5G for tin, tin ore resources guarantee ability is not optimistic. To improve the support capability of tin ore resources in our country, this article put forward to accelerate the development of tin ore exploration abroad layout, strengthen the domestic tin ore resources basic geological survey and exploration work, enhance the level of tin ore resources development and utilization technology, improve the efficiency of resource utilization etc.
