English term or phrase: downgrade stream
A known method is fractional crystallisation, which can be applied to purify e. g. an aluminium alloy contaminated with an alloying element such as iron. In fractional crystallisation an input stream of an aluminium alloy scrap material, which, for a certain alloying element or contaminant, is hypoeutectic in composition, is split into a first output stream or product stream of purified aluminium and a second output stream or *downgrade stream*, which is more contaminated with the contaminant than the input stream and has a composition closer to the eutectic composition for the contaminant.
Where in this description reference is made to fractional crystallisation, this is to be understood as comprising all forms of fractional crystallisation and all other purification methods starting from a hypoeutectic alloy, whereby the composition of the *downgrade stream* is determined by the eutectic composition of aluminium and an alloying element.
