Abstract

A process for preparing calcium oxide from gypsum comprising the steps of mixing gypsum with an alkaline solution, where the alkaline solution concentration ranges from 0.1 M to 2.5 M to form a mixture, stirring the mixture, isolating hydroxide salt obtained, drying the hydroxide salt at a temperature ranging between 105?C to 110?C, crushing the hydroxide salt, and calcining the hydroxide salt at a temperature from 26?C to 600?C to produce calcium oxide. The most illustrative drawing: Figure 3
