RECOVERY OF GOLD FROM E WASTE

E waste production in great amounts and its problems, which challenge the field of waste and environment management stem from the increase in the production of electronic appliances, diversity seeking consumers and perishable products. The disposal of e waste into the environment is hazardous as they contain chemicals. The conventional methods of disposing these e wastes are irrelevant and have an adverse effect on the environmental conditions which is threat to life. Gold is one of the precious metals that can be extracted from the e waste. The present work aim to extract gold from e waste by aqua regia solution based hydro metallurgy method which includes a sequence of process that starts from the treatment of the e waste in HCL solution and ends up with the use of fire assaying technology to get the piece of gold. The outcome of the project successful with 0.05395gm of 23.76 karat and 99.01 % purity of gold extracted. X ray method is used to check the purity and karat of the gold
