Abstract (en)
[origin: WO9639290A1] Iron-rich material waste products, such as electric arc furnace dust, are formed with an organic binder into discrete shapes, such as briquettes and/or other solid shapes. The shapes can then be used in iron and steel making processes and the iron and heavy metal values in the waste product recovered.
