A recovering method of zinc component from an electric furnace dust and a method thereof are provided to drastically lengthen lifetime of reactor as a reactor inside be lining-processed with the acid-resistant substance. A manufacturing method of sulfate zinc comprises a step of providing an electric furnace dust and concentrated sulfuric acid to a rotary disk(32) of a reactor inside; a step of mixing the concentrated sulfuric acid of micro powder type and the electric furnace dust in order to produce the sulfate zinc; and a step of collecting reaction mixture, dissolving the mixture in the water and drying. |
