There's not enough olivine to even make a dent in CO2 levels. So this, while useful addition to arsenal against global warming, is nowhere near enough.

- tempestn 7y agoOn the page I linked to, they address the amount available, and it sounds like there's more than enough. Do you have other information? > Is There Enough Mineable Olivine? > Yes! > There is more than enough olivine for global scale CO2 removal for the foreseeable future. Olivine is the most abundant mineral in the upper mantle, making up over 50% of it. There large reserves all over the world found near the surface, in a formation called dunite, which consists of greater than 90% olivine. The current price is also attractive, at $25 a ton with the ability to go below $10 a ton with increased mining.
