Exergetic considerations on the recovery of metals from waste
- Bottom ash from municipal solid waste incineration (MSWI) consists of elemental metals in considerable amounts. The exergy of bottom ash was calculated to be some 100 kJ/mol, mainly as a result of the presence of elemental Fe and Al. From this it can be shown that the recovery of elemental metals Cu, Al and Fe is beneficial. The fine fraction <4 mm additionally contains chemically bound metals (oxides, carbonates, silicates). Separation prospects with techniques as in ore processing (flotation, density separation, bioleaching, hydrothermal solution) are discussed. Although the concentration of Cu compounds in bottom ash is in the range of today’s exploited ores the economic viability of the recovery of metal compounds is uncertain. For sufficient enrichment different concerted treatment steps are required.
