Sorting, crushing, sifting to shape and reduce the rock to aggregate, sand and gravel; Blasting Rock. As more than 80% of rock is reduced to small rock aggregate, gravel or sand, explosives are the preferred method, though not the only one, of loosening Mother Nature's grip on her rock beds.

The trick with these methods is making sure that the CO2 does not escape, so projects are monitored closely to ensure the CO2 remains sequestered. Above-ground mineralization is also commonly referred to as enhanced rock weathering (ERW). This technique involves crushing rocks and spreading them over large land areas.

First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher "breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can't fall through will remain to be crushed with the next gyration.

Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
