Aqueous carbonation of peridotites for carbon utilisation: a critical review

Peridotite and serpentinites can be used to sequester CO2 emissions through mineral carbonation. Olivine dissolution rate is directly proportional with temperature, presence of CO2, surface area of

Magnesium Leachability of Mg-Silicate Peridotites: The Effect on Magnesite Yield of a Mineral Carbonation Process

The aim of this study was to increase feedstock availability for mineral carbonation. Acid dissolution and carbonic acid dissolution approaches were used to achieve higher Mg extractions from

CO2 utilization in built environment via the PCO2 swing carbonation of alkaline solid wastes with different mineralogy.

The two-step carbon mineralization via PCO2 swing, that has been developed for Mg-bearing silicate minerals, may not be viable for highly reactive Ca- bearing silicate materials (e.g., concrete), and the precipitated calcium carbonate derived from waste concrete via a pH swing process showed very promising results with a high CO2 utilization potential as an upcycled construction material.

A review on ex situ mineral carbonation

A number of carbonation methods, parameters that control the process and future potential applications of carbonated products are explored, such as resolving the slow rate of reactions, necessity of large amounts of feedstock, and reducing the huge energy requirements to accelerate the carbonation reaction.

Geochemical Negative Emissions Technologies: Part I. Review

Over the previous two decades, a diverse array of geochemical negative emissions technologies (NETs) have been proposed, which use alkaline minerals for removing and permanently storing atmospheric

Testing and Validating Instruments for Feedstocks of Mineral Carbonation

Different feedstocks Dunite, Olivine and Lizardite are examined in this research using various measuring techniques such as TGA-MS, XRD and Quantitative XRD and EDS. Quantitative XRD results matched
