Abstract

The invention provides a method for realizing direct mineralization of carbon dioxide in air by using natural ore. The method comprises the following steps: S1, crushing and activating natural ore to obtain an activated ore raw material; s2, the activated ore raw materials are fed into a mineralization reaction system, and air is introduced into the mineralization reaction system for a mineralization reaction; wherein the mineralization reaction system is carried out by adopting a gas-liquid reactor or a gas-solid reactor. According to the method, the mineralization reaction activity of the natural minerals in the mineralization reaction system can be enhanced, so that the problems of relatively low reaction speed and the like caused by relatively low concentration of carbon dioxide in the direct mineralization process of air are solved, and the mineralization reaction speed of the natural minerals reaches 10-100g CO2 / m < 2 >. H; the air carbon dioxide fixing amount in unit time and unit reactor sectional area can be obviously increased.
