Answer:
Some rocks can superficially react with atmospheric carbon dioxide, forming carbonates.
The speed of this reaction depends on how good air and water are at removing the carbonate.
In the case of olivine, a mineral that is a mixture of the silicates Mg 2 SiO 4 and Fe 2 SiO 4 , ferric oxide and/or hydroxide is also produced. Photo here.
Pulverizing silicate minerals speeds up their capture of CO 2 . The reaction is one-way: barring a whole-Earth holocaust that, long after the last living thing had died due to overheating, would begin to turn the carbonates back into gaseous CO 2 and alkaline earth, that CO 2 is down to stay.
Inadvertently doing this while mining silicates is the carbon capture and sequestration (CCS) method that has been most practiced to date.
