Near-infrared Reflectance Spectra of Mixtures of Kaolin-group Minerals: Use in Clay Mineral Studies
-Near-infrared (NIR) reflectance spectra for mixtures of ordered kaolinite and ordered dickite have been found to simulate the spectral response of disordered kaolinite. The amount of octahedral vacancy disorder in nine disordered kaolinite samples was estimated by comparing the sample spectra to the spectra of reference mixtures. The resulting estimates are consistent with previously published...
متن کاملAssociated Minerals and their Influence on the Optical Properties of Jordanian Kaolin
Kaolin samples from Al-Disi kaolin deposits in southeastern region of Jordan are associated with mineral impurities, which impart color to this kaolin and adversely affect its application in paper and paint industries. The associated mineral impurities with kaolin were separated by deflocculating of kaolin particles in polymeric sodium polyphosphate solution. The crude kaolin, deflocculated kao...
متن کاملKaolin dust concentrations and pneumoconiosis at a kaolin mine.
Kaolin is removed from underground seams in the mining area to a processing area, where it is sliced, dried, and pulverised to make the finished product. A study was undertaken to determine the dust concentrations in various work areas and to assess the prevalence of radiographic and pulmonary function abnormalities in 65 workers at a Georgia kaolin mine. Respirable dust concentrations were hig...
متن کاملAdsorption of 2-picoline and 3-Amino-2-picoline onto Kaolin and Organo-modified Kaolin
The adsorption of 2-picoline (PC) and 3-Amino-2-picoline (APC) onto kaolin and organomodified kaolin was investigated. Tetraethylamoniumiodide (TEAI) was used as modification reagent. The sorbent was characterized by FTIR, XRD, SEM and BET methods. The influence of various parameters like contact time, PH, adsorbent dose and initial concentration of PC and APC was studied. The adsorption kineti...
