Kaolin 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 کاملSerum Changes following Kaolin Injections
1. The intoxication produced by the intravenous injection of inert substances such as kaolin is due to protein split products derived from the serum proteins. 2. The kaolin acts as an adsorbing medium for the serum antiferment, bringing about an alteration in the ferment-antiferment balance. 3. The intoxication is accompanied by an increase in serum protease, and of proteoses. 4. The serum lipa...
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...
متن کاملKaolin Processing Using Fuzzy Hydrocyclone Control
In many cases, the hydrocyclone control is desirable for efficient separation especially in case of changing feed conditions. Control concept based on exact mathematical models is not satisfactory due to the complexity of the physical process. In this case, fuzzy control is a suitable solution. The data are primarily derived from an optical sensor that monitors the outside view of the free unde...
