Calcium Carbonate Mineralization of Microalgae
Biological substrates catalyze the nucleation and growth of sparingly soluble salts however, the underlying mechanism is largely unknown. In the present study, the growth of calcium carbonate (CaCO3), on Acutodesmus obliquus (AO) microalgae was investigated.

Dehydroxylation of serpentine minerals: Implications for mineral carbonation [PDF]
This review examines studies on the dehydroxylation of serpentine minerals published in the open literature from 1945 to 2013, with brief description of earlier work. Presently, the energy cost and technological complications, required to amorphise serpentine minerals by dehydroxylation, prevent their large-scale application for sequestering of CO2 ...

Development of Ultrafine Mineral Admixture from Magnesium Slag and Sequestration of CO2
To upcycle magnesium slag solid waste (MS) as well as sequester CO2, a new wet carbonation process was proposed to activate the volcanic ash activity of MS and use it as an ultrafine mineral admixture for cement.

Behaviour of concrete and cement in carbon dioxide sequestration by mineral carbonation processes
Mineral carbonation of construction and demolition waste is a viable alternative for the reduction of CO2 emissions from industry. Concrete and cement, together with ceramic blocks, are the primary sources of calcium for mineral carbonation in which CO2 ...
