Dissolution and Precipitation of Clay Minerals under Geologic

Phlogopite served as a model for clay minerals in potential GCS sites. During the reaction, dissolution of phlogopite was the predominant process. Although the bulk solution was not supersaturated with respect to potential secondary mineral phases, interestingly, nanoscale precipitates formed.

Mica in Sheets: Phlogopite Mica vs Muscovite Mica

Mica is a naturally occurring mineral and there are 37 varieties. However, the two we work with are phlogopite, or green, and muscovite, or white, mica. These two forms of mica come in sheet form, in two grades, MFSSP (phlogopite) and MFSSM (muscovite).

Comparative study of strontium adsorption on muscovite

Dec 01, 2020 · Micaceous minerals are the natural materials that can block radioactive strontium (Sr) released in the environment, and their adsorption capacity and mechanism are highly divergent owing to the different properties of micas. In this work, we comparatively studied the adsorption of Sr(II) on three typical micas, muscovite, biotite and phlogopite.

DISSOLUTION PROCESS OF PHLOGOPITE IN ACID SOLUTIONS

In the 100 ml experiments, the priority in dissolution in the initial stage was in the order; K > Fe > Mg, Al > Si. This supports that phlogopite leaching is controlled by the mineral structure. At 80* and 50"C in the 20 ml experiments, the release of all elements except for K was nearly congruent.

Exploring the relationship between Th(IV) adsorption and the

Feb 01, 2018 · XRD patterns showed that phlogopite was indeed transforming into the vermiculite- and/or montmorillonite-like minerals during Th(IV) adsorption, which indicated that the adsorption of Th(IV) could enhance the weathering process of phlogopite. Such weathering process could be attributed to the intercalation of hydrated Th(IV) ions instead of K ...

Compressibility of 2 M 1 muscovite-phlogopite series minerals

Nov 12, 2019 · Muscovite (Ms) and phlogopite (Phl) belong to the 2:1 dioctahedral and trioctahedral layer silicates, respectively, and are the end members of Ms-Phl series minerals. This series was studied in the 2M1 polytype and modeled by the substitution of three Mg2+ cations in the Phl octahedral sites by two Al3+ and one vacancy, increasing the substitution up to reach the Ms.

What is Mica? - Cogebi

Phlogopite is similar structurally, but contains magnesium. Its name is associated with the Greek word for flame. As a sheet silicate (Phyllosilicate), mica has a special characteristic—it can be split cleft into very thin flakes of similar thickness. Their appearance is quite different, Muscovite being light colored, whereas phlogopite is dark.

This process suggests the rupture of the trioctahedral layers of phlogopite, with the formation of a new basal spacing of a hydrophobic type occupied by phenylphosphonic groups. Simultaneously, the mobile K + ions would be partially substituted by [Mg(H 2 O) 2 ] 2+ groups, a hydrophilic space of a vermiculite type thus being obtained.
