What is Recovery of Gypsum from Cement Dust about?

This patent describes a method for recovering calcium sulfate dihydrate (gypsum) from cement kiln dust through a precipitation reaction with sulfuric acid solution. The recovered gypsum can be used in cement production as a functional additive. The process also produces a fertilizer as a byproduct. Additionally, the method allows for the production of Portland cement using gypsum derived from the cement kiln dust.
