Vast quantities of gold could be salvaged from old mobile phones using a simple chemical method, a University study shows. Current methods for extracting gold from old gadgets are inefficient and can be hazardous to health, as they often use toxic chemicals such as cyanide, researchers say.Gold Recovery Process. For gold recovery, water and a cyanide such as calcium cyanide, sodium cyanide, or potassium cyanide, are added to ore or scraps to form a slurry. The gold will leach out and mix with the cyanide into a solution. Activated carbon is then used to separate and store the gold, which is removed as the final step of the process.To recover gold, silver and palladium from cell phones we first need to sink them in the chemical to remove the components. Doing so, we will get 1.gold plateds items, 2.ceramic capacitors, 3.chips. Now we use CN process, nitric process, cupellation process, pyrolysis and hydrometallurgy to get pure gold, silver and palladium.Gold recovery from waste mobile phones PCBs using ammonia thiosulphate leaching and copper cementation process by Ramphagane Frank Nchabeleng Thesis submitted in fulfillment of the requirements for the degree Master of Engineering Chemical Engineering in the Faculty of Engineering at the Cape Peninsula University of Technology
