| description | The invention provides a screening method of aluminum extraction ash. Comprising the following steps: collecting an original ash sample, preparing the original ash sample into an ash analysis sample, carrying out content analysis on combustible C, Al2O3, CaO and SO3 components in the ash analysis sample, and substituting the result into a comprehensive discriminant (I) for calculation: screening the ash according to a Q value, and when Q is less than or equal to 3.6, not taking the ash as an aluminum extraction raw material; and when Q is greater than 3.6, taking the ash residue as an aluminum extraction raw material. By applying the technical scheme, the screening result can be quickly obtained only by analyzing and determining combustible C and a small amount of components of the ash sample and substituting the combustible C and the small amount of components into the comprehensive discriminant, and then the ash which can be used for extracting aluminum is subjected to aluminum extraction according to the s |
