Olivine Milling Method

So for the mining, milling, and transport, we would only lose net .05 tons of CO2 from the 1.25 tons of CO2 that each 1 ton of weathered olivine removes. Does that make sense? And as for the cost of mining, milling, and transport of the rock, that is only about $7/ton in the USA based on a model for a 5,000 ton per day of volcanic type rock ...

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).

As the olivine weathering occurs, the alkalinity of the reaction causes the water's pH to rise to ~8.3 pH. When the current is stopped, a silica coating rapidly forms on the olivine, which greatly slows down the reaction. Without the olivine reacting and with CO2 continuing to enter through the open-air by diffusion, the pH drops down to ~8.1 pH.
