| titleOfInvention | Tellurium separation and recovery method |
| abstract | To provide a tellurium separation and recovery method capable of recovering tellurium in a high yield with a simple process. A selenium recovery step for separating and recovering selenium by oxidizing and roasting a first residue containing tellurium, selenium and a platinum group element obtained after recovering gold and silver from a metal smelting residue, and selenium The second residue obtained after recovering selenium from the first residue in the recovery step is dissolved in an alkali solution, and an alkali leaching step for leaching and recovering most of tellurium, and tellurium from the second residue in the alkali leaching step The third residue obtained after leaching and recovering most of the mixture is mixed with hydrochloric acid containing an oxidizing agent to obtain a mixed solution containing the remainder of tellurium and the platinum group element, and the platinum group element contained in the mixed solution A complex formation step for promoting the formation of a chloride complex, and a neutralization separation step for neutralizing the hydrochloric acid leaching solution separated from the mixed solution that has undergone the complex formation step to separate the remainder of the tellurium and the platinum group element from each other.
