China's mineral resources for casting are excessively dependent on foreign countries

The current development of the foundry industry in China is in a period of sluggish development. Due to the limited resources of various mineral resources in China, the dependence of the production of raw materials for the foundry industry in China is too high. In recent years, imports of major minerals such as petroleum, iron, copper, aluminum, and potassium salts have risen sharply and foreign dependence has remained high. The latest figures are: 54.8% for petroleum, 53.6% for iron ore, 52.9% for refined aluminum, and refining. 69% of copper and 52.4% of potassium salt, of which, the dependence of related materials such as iron, copper and aluminum has increased, making the development of China's foundry industry also affected by many uncertain factors in foreign countries, which is not only for the development of China's foundry industry, but also Not an optimistic thing.
