Flotation Behavior of Diatomite and Albite Using ...

The flotation behaviors of diatomite and albite using dodecylamine (DDA) as a collector were investigated and compared. The pure mineral flotation results indicate that the flotability difference between albite and diatomite is above 87% at pH 5.5 to 10.5. The recovery of albite improves with increasing DDA dosage at pH 5.5 to 10.5. In the same pH range, …

The unusually high albite content in some rock types of this and the other more evaporitic facies is a distinctive feature of the Gurumanas Evaporite Member. The albite is usually crypto- to microcrystalline and of very high purity (0.3% CaO, 0.1% K 2 O). It cannot be a primary mineral because it replaces carbonates in the submerging lake ...

Occurs in nearly all igneous rocks - very common in granites, rhyolites, pegmatites, and similar rocks. Albite tends to be more common than anorthite, with the exception of metamorphosed carbonates and amphibolite. Also very common in metamorphic rocks, with albite being common in low-grade metamorphic rocks. Also seen in sedimentary detritus.

Abstract. Congruent melting of albite, NaA1Si3Os, is found to be a surface-initiated process, with melt nucleating at external surfaces and internal cracks and cleavage planes. Melting rates are found to be within a factor of 5 of rates calculated by a normal growth model. The melting point of albite is shown to be in the 1100 ø to 1120øC range.

the replacement of plagioclase by albite occurs via an interface-coupled dissolution–reprecipitation process as suggested by Engvik et al. (2008). If such a process is indeed operating, all bonds, including those of the Si–O-Al framework, should be broken during the dissolution process and it is expected that the oxygen atoms exchange along
