Highlights
Rapid global technological developments have led to the rising production of electronic waste that presents both challenges and opportunities in its recycling
Gift shopping card, phone card, sim card, hotel room card involves great proportions. They generally include many precious metals in their body, including noble metals, and semi-noble metals; predominantly gold, silver, copper, etc. The aim of this experimental work is to recover the metals from the smart cards by hydrometallurgical processes namely acidic leaching (HNO3 and Aqua Regia) followed by precipitation and cementation
Three different types of smart cards; credit cards supplied from different banks, telephone cards produced for Turk Telekom, and sim cards from three different mobile service providers, are used in the experimental work
Summary
Rapid global technological developments have led to the rising production of electronic waste that presents both challenges and opportunities in its recycling. Gift shopping card, phone card, sim card, hotel room card involves great proportions These microprocessors generally include many precious metals in their body, including noble metals, and semi-noble metals; predominantly gold, silver, copper, etc. With consumers worried about touching surfaces during the coronavirus pandemic, the use of mobile payments and contactless credit or debit cards has significantly increased in this term [13]. The aim of this experimental work is to recover the metals from the smart cards by using the similar processes which have used in the recycling of WEEE’s
