Method for recovering metals from secondary materials and other materials comprising organic constituents

A method for recovering noble metals and copper from secondary materials and other materials with organic constituents, the method comprising the steps of:

• removing organic components from the secondary materials and other materials by treatment in at least one process chamber;
• preparing the secondary materials and other materials with organic constituents for a recovery process, wherein the recovery process is configured in at least two stages, so that at least one first metal and a second metal arc recoverable;
• controlling process variables of a first stage of the recovery process so that a thin fluid slag with a low viscosity, wherein the viscosity is at least 15 Pa·s., and a metal melt are formed;
• adding a slag generating substance;
• and providing a process gas treatment subsequent to the first stage of the recovery process to reduce amounts of combustible gases and pollutants, wherein a total amount of organic constituents is 5-60% by weight, a process chamber of at least the first stage of the recovery process is formed by a Top Blown Rotary Converter, wherein off gas has an oxygen content in a range of 6% to 10%, and wherein the Top Blown Rotary Converter has a peripheral velocity of about 1 to 3 m/s, and wherein in the first stage at least 10 t/h of the secondary materials are fed to the Top Blown Rotary Converter.
