<p>The present invention relates to a method for preparing a neutralizer for zinc smelting using secondary dust from a steel dust recycling process. More specifically, the present invention relates to a method for preparing a neutralizer for zinc smelting using secondary dust includes a step of washing secondary dust for more than once by supplying washing water to the secondary dust to remove fluoride ions and chlorine ions included in the secondary dust, wherein the amount of the washing water is three to five times as much as the weight of the secondary dust. The present invention allows the manufacture of a neutralizer for zinc smelting in a simple and economical way as the washing water is applied to the secondary dust to effectively remove fluoride ions and chlorine ions among the elements of the dust, which may be harmful to a neutralizer for zinc smelt.</p> |
