| Abstract: |
| Causes for difficult separation of copper and slag during treatment of waste printed circuit board by bath smelting technology were analyzed. Based on theoretical calculation and experimental verification, copper content in slag system of SiO2-CaO-FeO-Al2O3 is controlled below 0.7%. Direct cost for processing 1 ton of wasted printed circuit board is 1 200 RMB with predictable economic benefit and remarkable social and environmental benefit. |
