Aluminum recycling includes secondary aluminum recycling and primary aluminum production, and its application areas are different due to its different purity. secondary aluminum has more advantages in environmental protection and economic benefits due to its high recovery rate and low energy consumption, but to achieve 99.9% purity, it is necessary to treat the waste aluminum material and strictly control the aluminum dross treatment process.
◇ Efficient Recovery: The dross press can complete the aluminum dross treatment in about 40 minutes, greatly reducing the oxidation of aluminum, ensuring the output of aluminum, and the recovery amount can reach about 80%.

► Can 99.9% of aluminum be recycled?
1. The waste is crushed into small pieces and melted in a furnace to remove impurities.
2. The aluminum dross is separated by a dross press, and the separated slag is further refined.
3. The refined aluminum is cast into ingot, bar, billet, etc., to obtain high purity aluminum.
Although the purity of secondary aluminum is not as high as the primary aluminum, the energy consumption of secondary aluminum is low, the recovery rate is high, the process is relatively simple, the use of advanced aluminum dross press and other equipment and technology, the aluminum dross treatment and refining, can achieve 99.9% purity of aluminum, and the recovery process is more energy saving.
