METHOD FOR THE PURIFICATION OF A MOLTEN METAL

摘要

The invention relates to a method for the purification of a molten metal containing one or more foreign elements. The invention is characterised in that the molten metal is cooled to a eutectic temperature to simultaneously form purified metal crystals and crystals containing at least one foreign element, and in that at least some of the crystals containing at least one foreign element are separated from the purified metal crystals by using a solid-solid separation technique.
