Aluminum dross use and aluminum dross composition

 

Aluminum dross machine

 

Aluminum dross is the product that slag generated in electrolytic aluminium or cast aluminum production process by cooling and machining. Main content is aluminum (15%-20%), aluminum oxide and silicon dioxide

 

Aluminum dross composition will vary from different sources

 

Electrolytic aluminium dross

w(Al)25.58, w(Al2O3)31.55, w(SiO2)5.56, w(Na2O)2~3, w(MgO)2.0~3.0,  w(CaO)<2.00, w(FeO)+ w(MnO)<1.0

 

Cast aluminum dross

w(Al)10, w(Al2O3)50~60, w(SiO2)3.0~5.0, w(Na2O)1.0~1.5  w(MgO)2.0~3.0, w(CaO)1. 5~3.0, w(FeO)+ w (MnO)<1.0

 

The use of aluminum dross can recover aluminum metal from the aluminum dross; another use is as smelting furnace desulfurization.
