A method and apparatus for step-by-step retrieving valuable metals from waste printed circuit board particles. Many kinds of metals, most existing in form of elementary substance or alloy, are contained in the waste printed circuit boards. Molten metals are separated selectively by supergravity separation at different temperatures to achieve the step-by-step recovery. Tin-based alloys, lead-based alloy, zinc aluminum alloy, crude copper and precious-metal-enriched residues with different metal contents are separated out and collected on the condition of different temperatures (T=200300 C., 330430 C., 700900 C., 11001300 C.) and controlling the gravity coefficient (G=501000) and separation time (t=220 min) etc. Different metals or alloys can be separated quickly and efficiently and the residue concentration of precious metals can be obtained. The process is simple and low cost to provide an efficient way to recovery the enrichment of valuable metals from electronic wastes.
