And according to everyone else the cost is higher. I read into this a while back. Many articles have already made the rounds on HN, multiple times. The most commonly cited method is using olivine rock. If you consider the full life cycle: mining, crushing, transporting and spreading the rock, it is not as cheap as this guy's calculations. There are actual high quality publications on this but I cannot remember the ones I read. However you can find many if you search for "olivine weathering".
