  6 Carbon Mineralization of CO2 | Negative Emissions …

  The USGS reserve estimate for wollastonite includes data on skarns that are profitable to mine at $200-350/t of wollastonite (depending on purity and crystal shape) plus income due to sale of byproducts. When fully carbonated, a ton of wollastonite can store 0.33 tons of CO 2, so these costs correspond to $600-1,000/tCO 2.
