With the new development of mineral processing technology, metal recycle is no less than to create a new mine. Panzhihua iron tailings in Shichuan province, contains copper, nickel, titanium, vanadium and other useful components, which is equivalent to a large non-ferrous metal mines. Non-metallic minerals such as coal gangue and bulwark rock are together wealth, and have been mining to the...
