PROBLEM TO BE SOLVED: To provide a treatment method of zinc slime, by which a zinc slime (a mixture of a zinc hydroxide and another) generated in a non-ferrous smelting step and a chlorine-containing resin are recycled as a zinc smelting raw material, and also a zinc can be recovered as a zinc-containing solution, and at this time, a reaction temperature is several hundred degrees (for example, 300°C) or below.SOLUTION: A treatment method of zinc slime includes: a step where a zinc slime generated in a non-ferrous smelting step and a chlorine-contained resin are heated, pulverized and kneaded at a temperature of 300°C or below to obtain a mixture; a step where water is added to the obtained mixture to form a slurry and then the slurry is agitated; and a step where the obtained slurry is solid-liquid-separated to recover a zinc-contained solution. |
