Are all the oxides carbonated in the raw materials used? The material referenced here was dunite but this will go for any raw silicate material used as it will not be pure CaO, MgoO, or FeO. What happens to the rest of the materials? Are they wasted (if so where are they stored)? Or can the impurities be sold (if so for how much and as what)? • How do you separate these final products assuming there are substantial impurities in them? Is the efficiency purely based on MgO cabronation or the entire mineral (dunite) carbonation?
