TENORM: Coal Combustion Residuals | US EPA
· Radioactive materials that are naturally included in coal's composition are also combusted during this process. When combustion is completed, the naturally occurring radioactive materials mostly end up in fly ash, bottom ash and boiler slag . About 10 to 20 percent of fly ash, bottom ash and boiler slag consists of TENORM.

Environmental radiological risk assessment of a coal ash and slag ...
A separate assessment performed on an example of reference plants showed that the use of activity concentrations in organisms as input data can result in an order of magnitude smaller estimates of dose rates in comparison to activity concentration in coal and ash as input data. Our study highlighted the need for experimental data in radiological risk assessments to mitigate .

Recovery of cobalt from slag in a DC arc furnace at Chambishi, Zambia
The intention in this part of the process is to separate the valuable nonferrous metals from the iron and the gangue constituents present in the slag. The desirable area of operation is clearly somewhere in the region where the recovery of cobalt is high, and the recovery of iron to the alloy is still reasonably low.

Vanadium Recovery from Fume Dust and SlagSlag/Dross .
Vanadium is widely spread in earth crust. Vanadium extraction is achieved through the recovery of vanadiumcontaining flue dust and smelting slag. Apart from minerals patronite, vanadinite, sulvanite, sefstromite, vanadium titanuomagnetite ore, vanadium also exists in stonelike coal, crude oil and bitumen.

The Finished Part: Coal Slag
Boiler slag is the molten material (ash and incombustible) that is sent to a quenching water bath. The quenching process immediately fractures the molten material producing a coarse, hard, black, angular, glassy material sometimes call black beauty. This coal slag is used for a variety of industrial appliions including abrasive blasting.

Slag
The smelting of copper, lead and bauxite in nonferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as ironsiliebased slags. [10] Copper slag, the waste product of smelting copper ores, was studied in an abandoned Penn Mine in California, USA.
