Bottom ash is commonly separated by dry physical methods coarse screening, size reduction, magnetic separation, eddy current separation and using aging or washing to stabilize the residue in terms of leaching capacity. france isood example with some of its incinerators separating the ferrous metals directly on site.
Abstract. magnetic fractions were extracted from pulverized wastetoenergy wte bottom ashes usingombined wetdry extraction method. the resulting magnetic and nonmagnetic fractions were subjected to compositional, mineralogical, and redox state analyses by xray diffraction xrd, xray fluorescence, and xray photoelectron spectroscopy xps, respectively.
Dry separation method. in the dry separation method, approximately 10f isa waste were placed ineaker. an external circular neodymium magnet was held in place withagnetic retriever rod and directly introduced to the incense sticks ash and moved back and forth over it.

Bfa magnetic separation is economically evaluated. this study globally shows that it is possible to extract some magnetic particles from mswi boiler fly ashes. however, the magnetic particles only represent from 23 to 120 gkg of the bfa and, though they are enriched in fe, are composed of similar elements to the raw ashes.
Magnetic drum separator dry drum separators have been developed mainly for dry separation of ferromagnetic ores with particle sizes finer than 20 mm. in addition to this conventional application, the dry drum separator has foundide range of other applications such as iron and steel slag treatment. reduced pyrite ash separation.
The separation of magnetite from fly ash according to the invention utilizes wet drum magnetic separation and preferably includes both dry and wet magnetic drum separation, with the dry separation steps occurring prior to wet separation. dry separators typically maximize the quantity of magnetic material separated out of the raw fly ash feed.
Separation of remaining ferrous usually with magnetic head pulley. separation of nonferrous metals usually with an eddy current separator. the remaining material should be just plastics. quality control and baling of these materials can then follow. dry recyclables separation plant from magnapower equipment ltd on vimeo.
Magnetic separation. dry magnetic separation has proven to be ineffective due to the strong electrostatic attraction between pulverized ash particles. in most cases,arge proportion of the nonmagnetic fraction adheres to the magnet, and therefore, the isolated fraction is far from representative of the magnetic fraction.
In turn, lin et al. separated iron oxides from ashes using dry magnetic separation and found that iron content in magnetic fractions increases withise of magnetic field strength. while ree bonded with aluminosilicate phase noniron minerals are enriched in nonmagnetic fractions.
The highest rey recovery 58.69 and enrichment factor 1.1 were obtained in ashes withize fraction of 38 m. magnetic separation results showed that the nonmagnetic fraction contained more rey than the magnetic fraction. the enrichment factor and rey recovery in the magnetic separation step were 1.12 and 91.64espectively.
