Aluminium%20reducers - Import export

When we melt aluminum, it will form dross/aluminum oxide. how to reduce it back to aluminium, then? Update: reduce here DOES NOT mean to reduce the amount of dross, but to CHANGE Aluminium oxide to aluminium. Molten Aluminum Dross Reduction How to reduce aluminium loss in the melting There are many methods for aluminum dross recycling; also reducing the aluminum dross in production is a direct method to save the aluminum loss. At the same time, it can save energy for the coming dross recycling; it is the most direct one of the methods to save energy. The main reason for aluminum dross formation is the reaction resulting between high-temperature liquid aluminum and air in aluminum melting and molten aluminum conveying processes. In the formation, the conveying and stirring etc external mechanical force will promote the reaction, so dross generation intensified in this process.
