electronic waste is dependent on the age of the device; the thickness of gold contacts halved from ca. 1.0 mm in devices manufactured in the 1980s to 0.6–0.3 mm for those made in the 2000's.11 Pre-separation treatment of e-waste The processing of e-waste typically begins with a manually intensive dismantling phase, during which circuit-board
Several electrochemical separations have also been developed, including a process to recover gold from a cyanide leachate solution using a highly porous glassy carbon cathode; 94 99% of gold was recovered in 1 h due to the electrode's large porous surface area, high void volume, rigid structure and low resistance to fluid flow ( Fig. 9 ).

Step 1: Collect all your gold fingers and weigh them. This will be used at the end for a final yield. Step 2: Collect ALL of your safety items. Note: Anytime you are working with any of the chemicals, you should be wearing gloves and safety glasses or face shield. Dissolving Base Metals Step 3: Place all the gold fingers into a beaker.
E-waste contains significant concentration of gold which is 10 times more than its concentration in gold ores. It approximately contains 10–10,000 g of gold/ton, whereas the …
Global materials' and energy constraints and environmental issues call for a holistic approach to waste upcycling. We propose a chemically rational, cost-effective and environmentally friendly recovery of non-leaching gold from e-waste using aqueous chemistry with hydrogen peroxide, an environmentally benign oxidant, and lactic acid, a food chain byproduct.
The disposal of e waste into the environment is hazardous as they contain chemicals. The conventional methods of disposing these e wastes are …
