摘要

Process for recovering metallic secondary raw materials from consumed spark plugs comprises working up consumed spark plugs to recover first component fraction from end sections of central electrodes on combustion chamber side and optionally earth electrodes and front sides containing precious metals on combustion chamber side. Component fraction contains gold, platinum, silver and copper.
