在日本，铝浮渣中的金属铝通常通过所谓的金属回收机（MRM）进行物理分离来回收。大量的含有氧化物、金属铝、氮化物和盐的残余物作为MRM工艺的副产物可分解地产生。由于金属铝比相对易碎的氧化物和氮化物更粘稠，因此在MRM中破碎后它仍然较大。采用较容易的分离工艺从残留物中回收金属铝，将促进可持续的再循环。研究了铝浮渣渣的组成与粒度的关系，以期开发出一种简单易行的铝浮渣渣改质工艺。研究残留物的平均尺寸为100-200 µm。大于约200 µm的残留物具有较高的金属铝含量，而它们的氮化铝和氯含量较低。结果表明，采用所提出的筛选工艺可以很容易地提高残渣中金属铝的含量。
Metallic aluminum in aluminum dross is recovered in Japan generally by physical separation, using the so-called Metal Reclamate Machine (MRM). A large amount of the residue containing oxides, metallic aluminum, nitrides and salts is unavoidably generated as a by-product of the MRM process. Since the metallic aluminum is much more viscous than the relatively brittle oxides and nitrides, it remains larger after crushing in the MRM. Using of an easier separation process for the recovery of metallic aluminum from the residue would promote sustainable recycling. The relationship between the composition and the grain size of the residue was investigated to develop an easier technique for upgrading aluminum dross residue. The mean sizes of studied residues were 100–200 µm. The residues larger than about 200 µm had higher metallic aluminum content, whereas their aluminum nitride and chlorine contents were lower. It was confirmed that the metallic aluminum content of the residue could be easily increased by the proposed screening process.
