Abstract: 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.

Abstract: 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 (Fe2C); 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.

Abstract: A high compressive strength silica mortar to be used for the installation of constructs such as building inside and outside walls, the road pavement, a slope and planting trees in the roof and manufacturing method thereof are provided. The high compressive strength silica mortar is formed of 30 to 60 wt % of silica, 40 to 70 wt % of blast furnace slag, and the 15 to 35 weight parts of polycondensation regulator for 100 weight parts of dry mortar powder of these silica and blast furnace slag, and is solidified by generating C—S—H, C-A-H, amorphous Geopolymeric Matrix{Al2O3.mSiO2.nM2O.xH2O(M=K,Na,Ca)} and Zeolite in the mortar. In particular, the high compressive strength silica mortar exhibits the compressive strength of 70.0 MPa or more by vibration forming and curing for 12˜48 hours at 25 to 80° C. before removal of form and aging for 28 days, and can save energies because a firing process is not required.
