Jordanian bentonite was activated by hydrochloric acid at room temperature. FTIR, XRD, TGA, and BET surface area analyses of the samples were carried out to examine the structure of bentonite before and after acid activation. It is found that the octahedral cations were removed, which altered the chemical composition of the bentonite.
The present study deals with modeling of the effects of processing temperature (30–95°C), concentration of Bentonite (Bent) (1-5 g/L) and pH (3.5–6) on color, turbidity, purity, ash and invert sugar content of purified raw sugar-beet juice. The used
Bentonite - A flow diagram for bentonite processing is provided in Figure 11.25-5. Mined bentonite first is transported to the processing plant and stockpiled. If the raw clay has a relatively high moisture content (30 to 35 percent), the stockpiled material may be plowed to facilitate air drying to a moisture content of 16 to 18 percent.
