Product Information

Amongst these, incineration is widely accepted because of its small land footprint, huge mass and volume reduction, and, additionally, energy can be recovered in the form of heat and electricity [ 4, 5, 6].

This cluster is the most interesting for economic metal recovery due to the high Zn recovery with the lowest H 2O 2 consumption and low acid consumption (7. In the current trend towards a circular economy, where urban mining is prominent, FA has become an interesting source for metal recovery.Therefore, the Swiss authorities released the Ordinance of the Avoidance and Disposal of Waste (ADWO), which prescribes the recovery of heavy metals from FA prior to disposal [ 6]. This effect can be used to recover small NFe metal particles from the bulk stream (both wet and dry) [ 133]. The removal of Cu, Zn, Pb, and Cd by different studies using different chlorinating agents is 80–95%, 75–97%, 99% and 99%, respectively.

Approximately 30% Zn, 16% Pb, and 1% Cu of the annual import could be replaced by metal recovery from FA.Such an initiative for the effective separation and recovery of metals from fly ash was taken in Switzerland in 1997, acidic fly ash leaching (FLUWA process) in 1997, as described in detail by [ 115] is shown in Figure 3. million tons are incinerated, whereas, with a huge number of incinerators, up to 60% of MSW is incinerated in Jiangsu and Zhejiang province alone. Although the recycling of waste is increasing day by day in China, there are still some challenges to face, for example, insufficient municipal solid waste separation, MSW being the dominant waste, which has a high proportion of organic components, and the separation of domestic waste is also low [ 56]. Water washing treatment is not only effective for the removal of metal chlorides but also serves as the effective tool for reducing the sintering temperature and treatment time.
