It is an industrial facility specifically designed for extracting mineral resources. Usually located in areas with abundant mineral resources, advanced smelting technology and chemical treatment methods are used to convert ores into valuable metals or compounds. These facilities include crushers, grinding machines, smelting furnaces, electrolytic cells, and chemical treatment equipment, which can process various ores. During the smelting process, the ore is first crushed and finely ground, and then subjected to high-temperature melting in a smelting furnace to separate valuable metals. Chemical treatment further purifies the metal and removes impurities. They are also important forces driving regional economic development and technological progress.
