Introduction, to study alternatives to recycle and reuse solid waste, to extend the life cycle of materials, and to reduce the rate of extraction of natural resources to supply the industrial demand for raw materials.Host142 发表于 2025-3-27 19:53:28
Leaching Processes,onstituents by the contacting liquid leads to a leachate/percolate or extract composition that can be of interest for different purposes [.], such as the extraction of metals from solid waste through a suitable leachant. Leaching is a step in hydro- and electrometallurgical processes and has been alAdulate 发表于 2025-3-27 22:06:00

Pyrometallurgical Processing,ycling of e.g. copper, lead and steel. Metal casings, external cables and other materials (made of aluminum, steel or copper), separated from WEEE by hand sorting/disassembly, are usually sent to primary or secondary smelters. The process steps depend on the metal content of the secondary raw materi托人看管 发表于 2025-3-28 07:18:58
Electronic Waste Recycling,ed for the metal fractions because of the economical value of this fraction, non-metallic fractions are gaining more attention, since the disposal of such material in landfills, or the burning of plastics can be associated to high environmental contamination .
