| Popis: | Utilizing Electrical and Electronic products has imbibed into the habitual activity of every human being. This has lead to the increase in the yield of E-Waste. Due to the Existence of toxic substances in E-Waste, it needs to be handled carefully as it has adverse impact on the environment. The improper disposal of Electrical and Electronic Waste has caused some metals to accumulate in the air which degrades the atmosphere. Hence proper disposal or recycling of the scrapped Electrical and Electronic products is mandatory and of major concern for research. The E-Waste contains several materials like Gold, Silver, Copper, Iron…etc. Extraction of all these metals from the scrapped electrical and Electronic Products in an environment friendly manner is of utmost importance. Electro chemical, Pyrometallurgical, Hydrometallurgical and Bioleaching are the most efficient methods to extract metals. The principal metal present in the scraped electronic products is copper. In this research work, printed circuit boards of Desktop Computers are used to extract metals from them. The electrolysis process is carried out with selective anode and cathode to extract copper from it. The current density is optimized to get maximum extraction efficiency of copper. |
