Arctic News: Olivine weathering to capture CO2 and counter .

Jul 30, 2016 · 5. The use of the surf as a huge ball-mill The surf as the largest ball-mill on Earth. Milling of olivine (around 2 US /ton for milling olivine to 100 micron) is a cost that can be avoided if nature provides a zero cost alternative. We have carried out experiments with angular coarse olivine grit in a simulated very modest surf (5).

process of olivine mining

Mining, milling and spreading Enhanced weathering is literally a very down to earth method. It comes down to mining lots of Olivine rock, then milling it down to the level of sand, and subsequently spreading it in a humid place, where CO 2 will dissolve in water and react with the Olivine to be converted to bicarbonate.

Dissolution and carbonation of mechanically activated .

Finally the energy consumption during milling was evaluated in the context of CO2 sequestration. Over 60 olivine samples were prepared by milling including duplicates. Two dissolution experiments were performed, one at room conditions with 0.01 M HCl and one at 128 °C and 150 bar of CO2.
