The Mining Industry’s Role in Enhanced Weathering and Mineralization for CO₂ Removal

Environmental Science & Technology, 2023
Enhanced weathering and mineralization (EWM) aim to remove carbon dioxide (CO2) from the atmosphere by accelerating the reaction of this greenhouse gas with alkaline minerals. This suite of geochemical negative emissions technologies has the potential to achieve CO2 removal rates of >1 gigatonne per year, yet will require gigatonnes of suitable rock ...

Evaluating feedstocks for carbon dioxide removal by enhanced rock weathering and CO2 mineralization

Applied Geochemistry, 2021
Abstract Mineralogically complex feedstocks, including kimberlite, serpentinite, and wollastonite skarns, have vast capacities to sequester carbon dioxide (CO2) through enhanced rock weathering and CO2 mineralization. However, only a small reactive fraction of these feedstocks will be accessible for carbon dioxide removal at Earth's surface ...

Can earthworms enhance mineral weathering and thereby increase carbon sequestration?  

2022
<p>Negative Emission Technologies (NETs) are urgently needed if we want to keep global temperature increase below 1.5 °C. Enhanced Silicate Weathering (ESW) is a NET with as yet unknown potential to mitigate climate change. There are indications that ESW rates can be amplified by biotic activity, including that of earthworms.

Isolation ofPaenibacillussp. and Assessment of its Potential for Enhancing Mineral Weathering

Geomicrobiology Journal, 2012
One mineral-solubilizing bacterial strain designated KT was isolated from a soil in Henan Province, China. The full-length 16S rRNA gene sequence showed 95.2 to 96.7% similarity to the bacteria of the genus Paenibacillus, indicating that the strain KT belonged to the genus Paenibacillus.

Assessing mineral dissolution and secondary mineral formation during enhanced weathering on agricultural sites

Enhanced rock weathering (ERW) has the potential of being a comparatively cheap carbon dioxide removal method, as most infrastructure already exists. However, questions still remain on both dissolution rates of the feedstock added to agricultural fields, as well as processes that reduce the efficiency of the CO2 drawdown reaction.Such significant ...

Effects of enhanced mineral weathering on soil structure and organic carbon storage

Enhanced mineral weathering is a nature-based solution to reduce atmospheric and soil CO2 concentrations in agricultural settings. Spreading finely grained basalt on the soil leads to subsequent chemical reactions that alters soil properties by changing soil pH, nutrient availability and particle-size distribution.

Accounting of weathering enhancement by mafic mineral spreading for CO ₂ storage

Geochemistry: Exploration, Environment, Analysis
The reduction of atmospheric CO 2 is an urgent global issue in the mitigation of global warming. Carbonate acts as a carbon sink in Earth's surface layer, and the weathering of terrestrial silicates and the deposition of oceanic calcium carbonate and organic matter mainly determine atmospheric and oceanic carbon ...

Assessing Dissolution Rates and Passivating Layer Effects in Olivine Weathering for Enhanced Carbon Mineralization

2023
Olivine is an appealing material for the mineralization of CO2 due to its inherent susceptibility to chemical weathering in aqueous environments. This natural process involves the dissolution and subsequent reprecipitation of olivine, yielding silica and carbonate species as primary products.
