Abstract. Tailings from the Pea Ridge iron mine contain significant amounts of apatite, which has rareearth element values associated with it. In association with the recovery of rareearth minerals as a secondary resource, the US Bureau of Mines conducted an investigation on the recoverability of the rareearth minerals from the tailings.

F. Habashi, in Encyclopedia of Materials: Science and Technology, 2001. 1 Recovery from Zinc Sulfide Concentrates. During roasting of zinc sulfide concentrates in fluidized beds, the flue dust will be enriched in cadmium, indium, and thallium, but the bulk of these metals remain in the calcine. That is why the dust is added to the calcine during processing.
In this study, enrichment methods for coal fly ash (CFA) from Omsk thermal power station No. 4 (TPS4) were investigated. The magnetite and unburned carbon concentrates were obtained by magnetic separation and flotation methods. The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from to wt % compared to dry magnetic .

Mar 01, 2007· In USA and Canada the BF flue dust and the finer millscale are generally recycled through the sinter plant. However the steel making wastes have hitherto been almost entirely dumped, owing to their fineness and high Zn, Pb, and alkali content. Recovery of carbon and magnetite from blast furnace flue dust
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coalfired boilers together with the flue that falls to the bottom of the boiler''s combustion chamber (commonly called a firebox) is called bottom ash.
