This paper describes the process of mineral carbonation, where gaseous CO(2) is fixed in the form of inorganic carbonates, and silica forms a solid by-product. The process is similar to naturally occurring rock weathering and the reaction products are environmental friendly. The duration of direct mineral sequestration is too long, and can be reduced by using two-step process employing carboxylic acids as additives enhancing reaction rate.
