Hydrothermal synthesis of 13X zeolite by using feldspars …

Zeolite has good physicochemical properties such as adsorption, cation exchange, molecular sieving and catalysis to be widely used as selective scavengers of heavy metals from liquid effluents. In this paper, the synthesis method of 13X zeolite using fine granite dust (FGD) resulting from granite processing has been investigated. Both alkaline fusion method (770–830 …

[PDF] Raman Spectroscopic Characterization of the Feldspars

From their Raman spectral pattern, feldspars can be readily distinguished from ortho- and chain-silicates and from other tecto-silicates such as quartz and zeolites. We show here how well Raman spectral analysis can distinguish among members within the feldspar group. ... which is a product of extremely strong crushing of granite in a ...

Feldspar and Syenites

Feldspars are a group of tectosilicate rock-forming minerals. The syenites are a group of intrusive rocks rich in feldspar minerals, and, unlike granites, they have little or no quartz. The most important syenite is nepheline syenite. ... the beneficiation consists of crushing and density and magnetic separation.

Usingin vacuo crushing methods, both Cl- and K-correlated components of trapped 40 Ar have recently been identified in hypersolvus alkali feldspar and K-feldspar-bearing 'chert' and stromatolite samples. If these components re-emerge during the late stages of thermal degassing, interpretation of 40 Ar/ 39 Ar age spectra could be complicated. We have extended …

Basic Introduction of Feldspar | Mining Pedia

Flotation is one of the most common processes used in feldspar separation. The method mainly uses the difference in buoyancy between feldspar and other minerals to separate feldspar from other impurity minerals by adding chemicals to the pulp. The flotation method is usually divided into two stages: roughing and sel…See more on miningpedia

    • Basic Introduction of Feldspar | Mining Pedia

    The separation process of feldspar usually includes crushing, grinding and flotation. Firstly the raw minerals need to be crushed to facilitate the subsequent separation process. Crushing is usually carried out using equipment such as jaw crushers and cone crushers. After crushing, the raw minerals need to be ground for subsequent flotation.
