Method for extracting aluminum oxide from fly ash by one-step process

The invention relates to a method for extracting aluminum oxide from fly ash by a one-step process. The technique for extracting aluminum oxide from fly ash by an acid-process/alkali-process has the defects of long technological procedure, complex equipment and poor economic performance, and restricts the large-scale application. The method comprises the following steps: mixing fly ash and potassium sulfate in concentrated sulfuric acid to carry out granulation; roasting for activation at certain temperature; dissolving out the solid in water or sulfuric acid to remove solid residues; removing the impurity iron from the solution by a jarosite process; crystallizing the solution to obtain solid potassium aluminum sulfate dodecahydrate; roasting the potassium aluminum sulfate dodecahydrate to obtain aluminum oxide, potassium sulfate solid and sulfur trioxide gas; and washing the solid phase, and filtering to obtain the aluminum oxide product. The potassium aluminum sulfate solid is obtained by cooling crystallization, thereby lowering the energy consumption; the impurities can be effectively removed in the crystallization process, thereby reducing the investment for the impurity removal system; and the potassium sulfate and sulfuric acid can be recycled, so the economic benefit of industrial production is high.
