Of the 118 elements listed in the Periodic Table, about 75% (91) are metals.
The challenge of collection of e‐waste has been met in informal recycling, but not adequately in formal recycling. 6. In Table 2, the total value of several metals in large quantities of collected mobile phones and laptop computers is given for the year 2010 . Mobile phones contain over 40 different chemical elements including base metals, such as Cu, Ni, and Sn; specialty metals including Co, In, and Sb; and the precious metals Ag, Au, and Pd. Metals, mostly Cu, make up about one quarter of the metal content in each phone.
This situation has attracted the attention of several groups who are developing recycling processes for recovery of Nd from high performance magnets. S. S. ore deposits using a molecular recognition technology (MRT) process . The MRT procedure could also be used to recycle these metals. Hopefully, recycling efforts underway will bring some stability to the critical rare earth market by improving the supply‐demand balance for these important metals, which presently have a recycling rate of <1%.
