Introduction Heat treatment is a routine operation in food production since it effectively destroys microorganisms that cause spoilage in food, thereby increasing the shelf life of products. At the same time, high temperatures may have a negative

The uptake of137Cs and90Sr/90Y onto Syrian bentonite has been studed, using batch and column tracer techniques in order to investigate its utilization for aqueous radioactive effluent treatment. Parameters influencing the percent uptake considered and studied in this work are: nuclide concentration, pH of the aqueous phase, heat treatment and particle size. Leaching experiments using natural sea and ground waters were carried out on bentonite/cement composites. They demonstrated the effectiveness of calcination and cement containment.
H2SO4 and HCl processes accompanied by thermal treatments at different stages are described for the industrial extraction of alumina
from lateritic clay minerals, especially from kaolinite, an important component of lateritic bauxites. The effects of calcination
at high temperatures on the pretreatments of the raw lateritic materials, as well as on the thermal transformations of the
products (salts) resulting from the acid treatments of lateritic bauxites are analyzed. Beside energetic considerations, separation
methods of Al from Fe and from other lateritic-metallic components are emphasized in the extraction and purification processes.
The mechanism of a controlled HCl-extracting treatment performed on iron-bearing kaolinite is described, as well as its characterization
by IR and DTA ad hoc methods, enabling to distinguish between Al and Fe in the structure of lateritic kaolinite. The location
and quantification of Al in the structure of lateritic goethite is also considered.
