| titleOfInvention | Method for manufacturing Zinc sulfate and zinc oxide from the dust of the electric arc furnace |
| abstract | The present invention relates to a method for producing zinc sulfate and zinc oxide from an electric furnace dust, comprising a pretreatment step (step S1); A primary filtration step (step S2); A particle size adjusting step (step S3); An acid leaching step (step S4); A de-ironing and neutralizing step (step S5); A secondary filtration step (S6); A trace heavy metal precipitation step (step S7); A tertiary filtration step (step S8) for removing impurities remaining in the filter; The secondary high-purity zinc sulfate obtained through a filtration step (Step S8) (ZnSO 4) sorting to determine the crystallization or drying the solution, or the drying step (step S9), and; And a heat decomposition step (S10) of obtaining zinc oxide by heating the zinc sulfate (ZnSO 4 ) to obtain zinc oxide. The electric furnace dust is reacted in a sulfuric acid solution having a concentration of 10 to 30% Which can be utilized as a building material utilizing the photocatalytic function such as cement industry by recovering zinc sulfate 1-sulfate, zinc sulfate 7-hydroxide powder and high-purity oxide salt powder having high utility values and low-chlorination sludge cake not dissolved in sulfuric acid The reason for not being commercialized in the existing method is improved, and the whole amount is recycled, and zinc sulfate and zinc oxide which are highly useful in industry are manufactured and recovered, and the recovery rate of the zinc component contained in the dust is improved by simple and simple steps It is a useful invention that has a special advantage that it can raise more than 90% and is excellent in economy. |
