Dissolved silica-catalyzed disordered dolomite precipitation
American Mineralogist, 2022There is a great abundance of sedimentary dolomite in the Proterozoic and Lower Paleozoic, but examples of primary dolomite are scarce in the Cenozoic.

Efficient removal of tar employing dolomite catalyst in gasification: Challenges and opportunities.
Science of the Total Environment, 2022Fossil fuels are currently the dominant source of electricity and energy production around the world. Biomass is one of the most referred renewable carbonaceous resource(s) that can be employed for the waste-to-energy concept.

A Raman spectroscopic comparison of calcite and dolomite [PDF]
Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2014 Raman spectroscopy was used to characterize and differentiate the two minerals calcite and dolomite and the bands related to the mineral structure. The (CO3)2− group is characterized by four prominent Raman vibrational modes: (a) the symmetric stretching,

An ion-tolerance collector AESNa for effective flotation of magnesite from dolomite
, 2021The separation of magnesite and dolomite has always been a difficult problem in flotation production, one of the reasons is that the dissolved Ca2+ ions from dolomite weaken the anionic flotation selectivity.

Dolomitization and the causes of dolomitization dolomite reservoir
Chinese Journal of Geochemistry, 2012This paper utilizes multi-methods, such as core observation, slice identification, isotope analysis, trace element analysis, fluid inclusion technique and so on, to study the causes of the dolomite in the Nanpu Sag and the origins of the dolomite reservoir.

A global study of dolomite stoichiometry and cation ordering through the Phanerozoic
, 2021Various geochemical proxies are used to constrain the diagenetic origin and evolution of ancient dolomites. Dolomite stoichiometry (mole % MgCO3) and cation ordering, two mineralogical attributes that define dolomite, have also been shown to ...

Structure, genesis and resources efficiency of dolomite: New insights and remaining enigmas
Chemical Geology, 2021Dolomite can form the major mineral component of marlstones, and limestones and is an important sink for Magnesium in the different geogene environments such as oceans. The Mg-distribution in the Earth crust and mantle is partly controlled by dolomite in
