Olivine weathering in soil, and its effects on growth and ...

Olivine increased soil water pH and alkalinity, plant uptake of Mg, Si and Ni, as well as bioavailability of Mg and Ni in soil. Olivine clearly suppressed Ca uptake which is attributed to competition by Mg. All these effects increased with higher olivine doses. There was a slight negative effect on P content in plant biomass at high olivine doses.

Mineral carbonation and industrial uses of carbon dioxide

far is the wet carbonation of the natural silicate olivine, which costs between 50 and 100 US$/tCO 2 stored and translates into a 30-50% energy penalty on the original power plant. When accounting for the 10-40% energy penalty in the capture plant as well, a full CCS system with mineral carbonation would

Coastal spreading of olivine to control atmospheric CO2 ...

Mining, crushing and grinding of olivine to a grain size of less than 10 μm will reduce process efficiency by 5–11% for pure olivine and by 10–20% for typical olivine rock. An additional 0.1–1% efficiency reduction will be generated per 100 km of transport of 1 tonne of crushed olivine rock by ship, train, or truck.

Grinding methods to enhance the reactivity of olivine

grinding methods were nearly as effective at size reduction without concurrent increases in surface area. Some large particles remained after dry attrition grinding, as shown by sample AM-D's D80 value of 16.23 !-lm. This large D80 value is thought to be due to trapping of grains in "dead zones" of the mill that have no grinding action.

Enhanced weathering of olivine as a cheap and …

Existing olivine mines should increase their production, and new olivine mines should be started. One should mine the olivine, and grind it to the required size (below 100 micron). Grinding of rocks is a standard operation in mining, and ball mills or vertical mills (roller mills) can be found at every mine.

Influence of the olivine additive fineness on the ...

Grinding tests in pilot scale show that if the olivine additive is ground in closed circuit with a ball mill keeping good control over the top size, the olivine fineness can be appreciably decreased without disturbing balling. The olivine reactivity can be decreased by 40% compared to the reference olivine in the production plant.
