aluminium smelter dross

When melting scrap melt loss and dross generation occurs It is estimated that in the US an energy loss of roughly 70 trillion BTUs per year results from oxidative melt loss of over 960 million lbs of aluminum and its alloys As dross generation is inevitable when melting aluminum the only controllable factors are the amount of dross generated and the amount of recoverable metal in the dross
