Recovery method and recovery apparatus of thallium in cement production facilities |
| abstract |
A recovery method of thallium in cement production facilities include a collection step of collecting dust in a combustion gas at a flow path for the combustion gas, which is at the downstream side of a gas-outlet of a suspension preheater 1 of the cement production facilities or a gas-outlet of a demineralizer of a cement kiln 3; a water washing step of washing the collected dust with water, to thereby obtain a slurry or aqueous solution; and a filtration step of performing a solid-liquid separation of the slurry or aqueous solution, to thereby recovery the thallium, wherein the thallium contained in the combustion gas that is discharged from the cement production facilities is recovered. |
