Carbon mineral ecology: Predicting the undiscovered minerals of carbon

American Mineralogist, 2016
Studies in mineral ecology exploit mineralogical databases to document diversity-distribution relationships of minerals—relationships that are integral to characterizing “Earth-like” planets. As carbon is the most crucial element to life on Earth, as well as one of the defining constituents of a planet’s near-surface mineralogy, we focus here on the ...

A quantitative separation of non-carbonate minerals from carbonate minerals

Journal of Sedimentary Research, 1964
Abstract Carbonate minerals can be separated from non-carbonate minerals by the use of 10 percent hydrochloric acid at room temperature for 24 hours. Clay minerals and pyrite are almost completely insoluble under these conditions. Gypsum, however, is soluble under the conditions used to dissolve carbonate minerals.

Accelerating Mineral Carbonation Using Carbonic Anhydrase

Environmental Science & Technology, 2016
Carbonic anhydrase (CA) enzymes have gained considerable attention for their potential use in carbon dioxide (CO2) capture technologies because they are able to catalyze rapidly the interconversion of aqueous CO2 and bicarbonate. However, there are challenges for widespread implementation including the need to develop mineralization process routes for ...

Carbon Dispersion and Morphology in Carbon–Mineral Adsorbents

Journal of Colloid and Interface Science, 2000
Carbon-mineral composite adsorbents prepared by deposition of carbon on various mineral supports have been studied extensively by a new textural approach. The evidence of significant influence of both organization of initial mineral support porous space and mobility of carbon precursors over the surface of mineral support on carbon localization has ...

Carbon dioxide disposal in carbonate minerals

Energy, 1995
Abstract We introduce a safe and permanent method of CO2 disposal based on combining CO2 chemically with abundant raw materials to form stable carbonate minerals. Substantial heat is liberated in the overall chemical reaction so that cost will be determined by the simplicity and speed of the reaction rather than the cost of energy.

The Role of Carbonate in Dental Mineral

Caries Research, 2009
The mechanism by which calcium-deficient hydroxyapatite can become carbonate apatite has been investigated by means of a monofluorophosphate competition experiment, measurement of phosphate exchange and uptake of 14C-labelled bicarbonate in the presence of various concentrations of orthophosphate.
