The actual situation of the recycled waste aluminum materials is that the waste aluminum materials can be polluted by oil sludge and other impurities, and are folded, corroded and doped with other metals. Therefore, in order to facilitate the subsequent smelting, the recycled waste aluminum materials need to be classified and cleaned.

In order to realize the classification and the cleaning treatment, a flotation technology in the mineral separation technology is generally adopted, namely ferrosilicon powder and water are mixed to form medium liquid for flotation, and then the waste metal needing to be classified and cleaned is integrally added into the medium liquid. Different metals have different densities, so that the different metals are layered in a medium liquid for flotation, and the layered metals are directly sorted, so that the rough classification of different types of metals is completed.

As the waste metal is overlapped and bent, a large amount of ferrosilicon powder is remained on the main recovered metal (different from the metal regarded as impurities) after the ferrosilicon powder medium liquid is floated, the main recovered metal with the large amount of ferrosilicon powder is generally and directly smelted in the prior art, and the practice shows that the quality of the smelted metal is not high and the high-requirement metal product requirement cannot be met. This is the case, for example, in the recycling of waste aluminium materials.
