The international trade of mineral products is increasing as a demand for mineral products. According to UN Comtrade's disclosure information, this paper applies complex network theory to calculate the density, node degree, centrality, node strength and path length of complex network of international mineral trade, and studies its evolutional rule. The results shows before the US subprime mortgage crisis in 2007,a tightness of mineral products trade rises with importer and exporter numbers. US, China, Germany, South Africa, UK and Canada hold vital positions, intensifying their export capacity in mineral products. Impacted by the financial crisis, mineral products trade dropped. After 2009, the global economy rebounds with a speeding globalization in mineral products and a very strong ascending of mineral products trade, obviously forming regional tycoons.

Diatomite as a kind of biogenic siliceous sedimentary rock is widely distributed in the world, but less with high economic values. China, abundant in diatomite resource, is one of major diatomite producers. In diatomite product structures, however, China has a big gap. As power saving and environment requires, China's diatomite product structures will be largely improved. The dominant developing trends for the diatomite industry include top-quality diatomite filtration, functional fillings and compound materials, insulation materials, water treatment agents and absorbent, and purification materials. China's diatomite industry must focus on extensive utilization, renovation and industrial platform construction.
