The magnetic separator plays a role in improving the grade of ore, purifying solid and liquid materials, and recycling waste.
The fly ash from most of the U.S. bituminous coals contains 15 to 20 weight percent iron oxides, 50% or more of which can be recovered by dry magnetic separation as a high density fraction. The density of this fraction is 3.5 to 4.0 g/cm/sup 3/, depending on the fly ash. Most of the particles are spheroidal,...
Nanohybrids with magnetic iron-oxide nanoparticles (FeNPs) embedded in the multilayered silicate clay were synthesized by in situ Fe2+/Fe3+ coprecipitation. The natural clay, sodium montmorillonite (Na+-MMT), was first modified with hydrophobic poly(oxypropylene)amine …
The early detection of Legionella in water reservoirs, and the prevention of their often fatal diseases, requires the development of rapid and reliable detection processes. A method for themagnetic separation(MS) of Legionella pneumophila by superparamagneticiron oxidenanoparticles is developed, which represents the basis for future bacteria detection kits.
