Sequential extraction of aragonite, calcite and dolomite from eastern Mediterranean sediments Abstract – A novel sequential extraction method for carbonates (CASEX) has been developed to differentiate between aragonite/calcite and dolomite. Dolomite can be reliably quantified as shown by the extraction of a prepared standard of known mineral ...

Ca converts into aragonite fiber with high aspect ratio, and Si converts into fiber-shaped mesoporous SiO2 with high specific surface area. In a word, Si, Al, Ca and Na in CGA are divided and recycled during three processes: water leaching, hydrothermal leaching and CO2-pressured leaching.

Aragonite and calcite have the same chemical formula, CaCO 3, but their atoms are stacked in different configurations. That is, they are polymorphs. (Another example is the trio of kyanite, andalusite, and sillimanite.) Aragonite has an orthorhombic structure and calcite a trigonal structure. Our gallery of carbonate minerals covers the …

Ca transforms into aragonite fiber with high aspect ratio, and Si transforms into fiber-shaped microporous SiO 2 with high specific surface area. In a word, Si, Al, Ca and Na in the CGA is divided and recycled during three processes: water leaching, hydrothermal leaching and CO 2 -pressured leaching.
