Provided is a dry separation apparatus including: a main body; a first deck; a plurality of guides; a supply part; an air blow fan; and a vibration part. A dry separation method includes: supplying an object to be separated to a top surface of a first deck provided with a plurality of punches; sending, by an air blow fan, air to the punches (first punches); and horizontally vibrating, by a vibration part, the first deck so as to discharge particles which have different specific gravities of the object to be separated and a moveable force exerted by air passing the first punches through different passages.

Dry separation apparatus and dry separation method

The present invention provides a method of separating and recovering iron from a waste non-ferrous slag, generated in a process for smelting of non-ferrous metals, including copper, zinc and lead, in which a reducing agent and a reaction catalyst are added to the crushed waste non-ferrous slag, and the mixture is subjected to a reduction reaction, thereby converting amorphous iron oxides, bound to alumina, calcium oxide, magnesium oxide, silica, and the like in the waste non-ferrous slag, to crystalline iron (Fe) and iron carbide (FeC); the resulting material is crushed to separate iron and iron carbide obtained by the reduction reaction from components such as alumina, calcium oxide, magnesium oxide, silica, and the like; the crushed material is separated into fractions by particle size; and the fractions are subjected to wet magnetic separation and dry magnetic separation to separate and recover magnetic iron concentrates from the fractions.
