Inertizationof pyrite cinders and co-inertization with electric arc furnace flue dusts by pryoconsolidation at solid state

摘要

The viability of a pryoconsolidation process to render pyrite cinders inert and to co-inert pyrite cinders with a hazardous poly- metallic residue such as electric arc furnace flue dusts (EAF) containing Pb, Cu, zn, As, Cr, Ni and Mo were investigated. The effects of pyroconsolidation temperature (800-1200 deg. C), milling pyrite cinders and additions of both CaO and EAF on the resulting microstructure of the pellets were determined. The microstructural changes were then compared with the results of the standard leaching tests.
