Zinc ore international trade pattern is changing continuously as international trade surges. In an attempt to provide references in making zinc trading policies, this paper uses international zinc ore trading data from 2010 to 2019 to establish a directional weighted zinc trade complex network with countries as nodes and trade links between countries as edges, with which its evolution is analyzed and key and pivot nations are identified. The results show that zinc trade size is escalating. The number of countries participating in trade is increasing, and trade tends to be globalized. China's zinc ore trading size has been ranked number one for many years and China is in the center of trading. It suggests China should enhance cooperation with Australia and Peru in import and boost metallurgical technologies so as to guarantee its zinc ore supply.
