Selenium induces a multi-targeted cell death process in

Both selenite and selenodiglutathione exhibited equipotent toxicity (IC50 5 μM) in these cells with striking differences in toxicity mechanisms. Morphological and molecular alterations provided evidence of necroptosis-like cell death in selenite treatment, whereas selenodiglutathione induced apoptosis-like cell death.

Influence of inherent iron and oxygen concentrations on selenite …

The oxygen concentration and inherent Fe in bentonite have a significant influence on the Se(IV) sorption process. In this study, the sorption of selenite on natural bentonite was investigated using a batch experiment method, and the distribution coefficient (K d) values were obtained in the pH range from 2.0 to 10.0 under oxic/anoxic conditions. …

Explaining the Process of Froth Flotation

The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …
