Table 1 summarizes the detailed BET analysis information of kaolin, Fe 3 O 4, and FKC.Obviously, the surface area of FKC increased with the increase of FeSO 4 concentration. When FeSO 4 concentration is 0.1 mol/L, the surface area of FKC is largest. The surface area of fresh FKC (133.7 m 2 /g) increased significantly when compared …
This paper studies the extraction of aluminium from kaolin through leaching process, using aqueous solutions of acids and bases, as leaching agents. For this study, crude kaolin excavated in Milos Island, Greece, was used. Before leaching, crude kaolin was calcined; calcination achieves the dehydroxylation of kaolinite, which is the main ...
The poor barrier of cellulosic paper against water vapor and oil limits its wide application as a packaging material. Lamination, extrusion, and dispersion coating are applied on paper surface to improve barrier properties. Dispersion coating can be applied to paper surface on line during paper preparation using rod coater. In the present study, an attempt has …
Dry process is a simple and economical processing technology. After the mined raw ore is crushed to 25.4mm by the hammer crusher, it is fed into the cage crusher to reduce the particle size to 6.35mm. The hot air in the cage crusher reduces the moisture of the kaolin from 20% to 10% or so. The crushed ore is further ground by an air-blown ...
