Abstract
PURPOSE: To recover aluminum of high quality from a molten alloy effectively by a method wherein an Al-Si alloy prepared by reduction refining method using a blast furnace is absorbed in molten lead and then the alloy and the lead are separated from each other as layers.
CONSTITUTION: Alumina-based coked briquets prepared by a predetermined method are charged into the blast furnace 10, where they are heated to a temperature of not lower than 2,000°C, whereby the alumina and silica contained in the briquets are completely reduced to form the Al-Si alloy. In this case, the molten lead is injected into the furnace 10 through a tuyere 13 so that the dropping alloy is absorbed in the molten lead, and the lead with the alloy therein is taken out from a basin 20 and is transferred into a retaining furnace 15. After the alloy and lead are separated from each other as layers by cooling them in the retaining furnace 15, the alloy is pumped up from the upper layer and is transferred into a deleading furnace 18, where the minute amount of residual lead is completely separated off by vacuum fractional distillation. Then, the degree of vacuum is enhanced to separate the aluminum and silicon from each other.
