Pressure swing adsorption provides separation of oxygen or nitrogen from air without liquefaction. The process operates around ambient temperature; a zeolite (molecular sponge) is exposed to high pressure air, then the air is released and an adsorbed film of the desired gas is released.

The introduced Fe 3 O 4 resulted in high performance of magnetic separation and also played the role as adsorption sites for phosphate. FeC-H and FeC-P demonstrated higher sorption capacity than bare Fe 3 O 4 due to the highly dispersed and smaller crystalline sizes of Fe 3 O 4 particles loaded in corn stalk derived-biochar support.

(these are the only areas on a magnet bar which extract and retain weakly magnetic fragments). Consider also how far in from bar end is the first 10,000 to 11,000 gauss pole centerline. This is where separation begins and is governed by the length of first magnet, width of pole plate and the length of the end plug retaining the magnets. 4.

MBC loaded with γ-Fe 2 O 3 not only has excellent magnetic separation ability, but can also reach about 80% of the initial adsorption capacity after four cycles of adsorption.

Jul 18, 2018 · Instead, magnetic oxides demonstrated a significant shortage of oxygen atoms around Fe, Zn, and Cr, i.e., oxygen vacancies which increased from a single oxide phase (for example, Fe 3 O 4 or ZnO) to Zn-Fe 3 O 4 -SiO 2 and further to Zn-Cr-Fe 3 O 4 -SiO 2, resulting in a significant increase of catalytic activities of these magnetic oxides (Oracko et al., 2017).

The maximum oxygen purity achieved, 42.10%, is from the periphery of the vortex tube at a cold fraction of 80% with an applied magnetic field. Oxygen purity increases out of both the core and periphery of the vortex tube with increasing cold fraction. The oxygen purity is related to the oxygen yield.

Cyanide leaching of gold is a common step used in the separation between gold concentrate and gangue minerals. Generally, the common gold extraction processes mainly include gravity separation, flotation, magnetic separation and electric separation, and the low grade gold concentrate obtained by the above gold extraction processes can be further processed using cyanidation method.
