Abstract :
    Computer chips hold valuable metals such as gold. Recycling operation of these elements is more than 6% more economical than their extraction in terms of energy consumption. Since gold consumption is increasing, and its various uses are in high demand for the use and consumption of gold, its recovery is quite essential. This importance of recovery necessitates using simpler gold recovery methods. One of the most significant technologies in contemporary decades is the recovery of gold from primary and secondary sources such as ore, lychee solutions, electronic waste, and plating effluent solutions. Also, due to the very high ductility of this metal on a nanoscale and the many applications of these particles, with a novel method in this research, gold nanoparticles were prepared using gold waste (electronic board s), aqua regia as the solvent, and iron sulfate as the gold revitalizer agent.
