Gold Recovery from E-Waste by Porous …

Gold recovery from electronic waste could prevent excessive mining with toxic extractants and provide a sustainable path for recycling precious metals. Unfortunately, no viable recycling is practiced, except burning electronic circuit boards in underdeveloped countries, mainly because of the lack of chemical scavengers as adsorbents. Here, we report the synthesis of a family of porphyrin ...

Optimization Studies on Recovery of Metals from Printed ...

The aim of the study was to recover copper and lead metal from waste printed circuit boards (PCBs). The electrowinning method is found to be an effective recycling process to recover copper and lead metal from printed circuit board wastes. In order to simplify the process with affordable equipment, a simple ammonical leaching operation method was adopted. The selected PCBs were incinerated ...

Electronics Recycling- Rich Source of Precious Metals

 · One metric ton of circuit boards can contain 40 to 800 times the amount of gold and 30 to 40 times the amount of copper mined from one metric ton of ore in the US. This e-waste is a particularly rich source of precious metals—with concentrations 40 to 50 times more abundant than naturally occurring in ore deposits.

Buyers of Gold, Silver, Platinum, Palladium, Electronics Scrap

Gold plated pins and other gold plated material is the highest yeilding e-scrap. The gold on these sources is typically present in higher quanitities and more readily recovered than other types of scrap material. This means a higher payout for you. Common sources include connector pins, circuit board fingers, manufacturing blanks and more.

 · A large socket motherboard is different from a metal socket GREEN motherboard, and a cell phone board is different from a circuit board found in a TV or DVD player. This is important to note because different types of circuit boards have various values — for example, on Boardsort.com, a large socket motherboard is worth $2.75 a pound, while a ...

Copper extraction from waste printed circuit boards by ...

1. Introduction. In recent years, the number of waste electrical and electronic equipment (WEEE) has increased rapidly. Between 2009 and 2014, the number of abandoned computers, telephones, televisions and appliances doubled to 42 million tons per year .The data show that the United States is the country with the most prodigious output of WEEE, while China ranks second .

Precious metal recovery from electronic waste by a porous ...

 · Electronic waste, also called e-waste, is rapidly becoming a major industrial hazard because of the increased use of circuits and screens. With the right technology, however, this waste could become a sustainable source for precious metals. Such a solution requires selectivity toward the precious metals, as this characteristic is even more important than capacity.
