The results show that the acidified albite hardly absorbs U (VI) at pH < 4, indicating that it doesn't affect U (VI) recovery in in-situ leaching process. However, the adsorption percentage of U ...
very interesting [35–38]. For instance, the mining of tin ores by a gravel pump or by dredg-ing produces a stable mineral suspension containing very fine particles as a waste, the so-called tin tailing slurry [45]. The very fine clay particles in the slurry settle to a compact sediment, as a waste, and water can be recycled in the process.
The results indicate that in the (Si-Al) disordering process Al enriches the Tlm site more than T2o and T2m sites. This trend continues until both Tlo and Tlm are occupied by 30% of Al, and T2o and T2m by 20% of Al. No evidence of complete disorder in T1 and T2 sites has been experimentally found to date. The (Si-Al) disordering process induces ...

Albite, common feldspar mineral, a sodium aluminosilicate (NaAlSi3O8) that occurs most widely in pegmatites and felsic igneous rocks such as granites. It may also be found in low-grade metamorphic rocks and as authigenic albite in certain sedimentary varieties. Albite usually forms brittle, glassy.
For example, when a heavy liquid (S.G. 2.5) was used, the concentration criterion between spodumene and various gangue minerals ranged from 2.00 to 11.8, suggesting that spodumene can be easily separated from albite (CC = 5.20), quartz (CC = 4.26), and K-feldspar (CC = 11.8); the separation of spodumene from muscovite may be …

Due to its abundant resources, stable properties and diverse application fields, albite is widely used in industry and life. Since the choice of mineral processing technology depends on the properties of the ore, in actual production, there are various types of albite mineral processing technologies, and the mineral processing plant should choose …

Chemistry: NaAlSi 3 O 8, Sodium aluminum silicate. Uses: ornamental stone, ceramics and mineral specimens. Albite is a common felspar and is the "pivot" mineral of two different feldspar series. It is most often associated with the plagioclase series where it is an end member of this series. The plagioclase series comprises felspars that range ...
