Aluminum and its alloys is an important raw material of economic construction, widely used in machinery, construction, automotive, aircraft, household appliances and packaging materials and other industries. After 80 years, the aluminum industry has developed rapidly over the world paint materials recycling, non-ferrous metals output ranks first in 2001, primary aluminum production reached 24.67 million tons, consumption reached 23.52 million tons. Primary aluminum industry has developed rapidly recovering silver nitrate chemical raw materials, but also bound by a long construction period, high investment, high energy consumption, serious pollution problems. To compensate for lack of raw materials recycling of primary aluminum development to meet growing market demand, countries have attached great importance to the development of recycled aluminum, recycled aluminum and its products have been widely used in various industrial fields. 1.
