Recovery of valuable materials from fine industrial waste streams
MetadataShow full item record
The recycling of metals from waste streams is important since natural resources could be conserved by recovering metals from secondary sources. Moreover, environmental problems due to the waste disposal also could be alleviated by removing volatile and toxic materials from the wastes. In general, high-temperature materials processing generated off-gases contain a large amount of dust. Therefore, dust collection systems, such as baghouse and cyclones, are usually installed in these facilities to control the emission of air pollutants. Dust collected from various facilities usually contains some ...
