| Abstract Scope |
Printed circuit boards, collected from Bangladesh, were melted to determine the proportion of metal, ceramic and volatile components. The concentration and amount of valuable elements in the e-waste was calculated from the analysis of the metal and ceramic phases. This information was used to design a simple three stage process to recover the valuable components. The three stages included primary smelting, electro-refining of a crude copper rich anode and smelting of anode slimes. In this process copper would be recovered as a high purity cathode and silver and gold recovered as a precious metal bullion from the processed anode slimes. Tin and other valuable elements such as rare earth elements reported to a slag phase. The operating and capital costs of these three operations were estimated and the financial viability of the process estimated. The results showed that the process could be economical at present metal values. |
