Zusammenfassung:	The invention discloses a zinc-copper-tellurium-bismuth-indium containing material separating method. The zinc-copper-tellurium-bismuth-indium containing material separating method comprises the following steps that firstly, a water solution is used for slurrying reducing slag, then, industrial concentrated sulfuric acid is added for the reaction, in the reaction process, hydrogen peroxide is slowly added, and after the reaction is finished, solid-liquid separation is conducted, and filter liquor A and leaching slag are obtained; secondly, production water is used for slurrying the leaching slag, the industrial concentrated sulfuric acid is added for the reaction, in the reaction process, hydrogen peroxide is slowly added, and after the reaction is finished, solid-liquid separation is conducted, filter liquor B and bismuth concentrates are obtained, the filter liquor B returns to the first step, and slurry mixing liquid is made; and thirdly, iron powder is added in the filter liquor A,after the reaction is fi
