The present invention relates to a method for preparing a neutralizer for zinc smelting using secondary dust generated during a steel dust recycling process. The method for preparing a neutralizer for zinc smelting using secondary dust comprises a step of cleaning secondary dust one or more times by supplying cleaning water three to five times more than the weight of the secondary dust to the secondary dust in order to remove fluorine ions and chloride ions included in the secondary dust. Therefore, the present invention effectively removes fluorine and chloride, which can be affected poisonously when being used as a neutralizer for zinc smelting, from elements included in the secondary dust by applying the cleaning water to the secondary dust, thereby simply and economically preparing the neutralizer for zinc smelting. |
