Abstract: The preliminary studies of indirect aqueous carbonation process using fly ash from lignite fluidized bed combustion are presented. Leachate after the dissolution of waste of pH=13 contained 0.0535 mol•l-1 of Ca+2. The experimental research were conducted for a mixture of nitrogen and carbon dioxide, with about 13% of CO2. After 9 minutes of conducting the process a 50 % conversion of calcium was attained, and almost 100% of carbon dioxide supplied to the reactor was captured.
