Do any useful materials tend to occur alongside olivine? If so, using tax incentives to ensure that open cast mining takes place in olivine-rich areas would potentially help greatly. Coarse-ground mine tailings dumped in areas prone to erosion would eventually end up weathering pretty fast.
This could be a very simple way of getting some pretty large volumes of CO2 out of the air.
