Abstract

Conventional and advanced/novel WPCB and e-waste recycling processes are introduced and compared in this chapter. Traditional uncontrolled incineration and mechanical separation (i.e., gravity separation) methods are covered. Novel pyrometallurgical methods for WPCB recycling include direct smelting, incineration, physico-mechanical separation, vacuum pyrolysis, and gasification. Limitations and emerging technologies in pyrometallurgy are also presented. Industrial pyrometallurgical processes for the recovery of metals from e-waste are stated. Hydrometallurgy, purification, solvent extraction, ion exchange, and electrowinning are explained in detail. Advantages and disadvantages of base metals, precious metals, brominated epoxy resin, and solder stripping solvents are compared. Possible chemical reactions between metals and reagents are presented. Finally, water treatment processes are mentioned shortly.
