Abstract

With the developing technology in recent years, the variety and production of electronic products has increased rapidly. The amount of unused products increases with high consumption rate, these products are disposed as scrap. These types of scrap, called electronic waste, cause serious damage to the environment and livings due to the harmful elements and components. Apart from harmful compounds, the high content of precious metals in e-waste compared to the natural sources makes them very attractive for metal recovery. Print circuit boards (PCB’s), which comprise 3% of the e-wastes, attract attention with high Cu, Au and Ag contents. Within the scope of this study, comminution and classification processes were applied and then shaking table was subjected to -2, + 0.5 and -0.5 mm fractions to recover Cu, Au, Ag from PCB’s. As a result of the enrichment tests, 62% wt. of the feed was obtained with 88.2% Au, 95.3% Cu and 93.6% Ag recoveries.
