E-waste is considered hazardous waste because it contains some heavy metals. Extraction and utilization of these metals is highly appreciated. Spent e-waste was used as an input material to prepare copper nanoparticles using up to 33% ammonia solution. The resulting solution was acidified by sulfuric acid to yield copper (II) sulfate. The substrate material was made of crushed glass coated with carbon film. The substrate particles were dipped in copper (II) sulfate solution. The reducing material was hydrazine hydrate and/or ascorbic acid. Results showed that ammonia has been proved to dissolve copper at 20^oC up to 90^oC. The extent of dissolution depends on concentration, temperature and time. Ascorbic acid to be more effective as compared to hydrazine hydrate to produce copper ions to metallic form. Particle size measurement showed that the copper particle size range from 26.22 nm to 400.9 nm with ascorbic acid, from  35.12 nm  to 669.7 nm with hydrazine hydrate and from  35.12 nm to 658.4 nm with mixture of them. Results were explored with the help of FESEM. Results have been found friendly, simple and economic process.
